Pappus of Alexandria Essays - Mathematics, Geometry, Free Essays

Pappus of Alexandria Essays - Mathematics, Geometry, Free Essays Pappus of Alexandria Pappus was born in approximately 920 in Alexandria, Egypt. He was the last of the great Greek geometers and one of his major theorems is considered to be the basis of modern projective geometry ("Pappus"). Pappus flourished in the fourth century, writing his key work, the Mathematical Collection, as a guide to Greek geometry ("Biography"). In this work, Pappus discusses theorems and constructions of over thirty mathematicians including Euclid, Archimedes and Ptolemy ("Biography"), providing alternatives of proofs and generalizing theorems. The Collection is a handbook to all of Greek geometry and is now almost the sole source of history of that science (Thomas 564). The separate books of the Collection were divided by Pappus into numbered sections. In the fourth section, Pappus discusses an extension on the Pythagorean Theorem (Thomas 575) now known as Pappus Area (Williams). Pappus drew parallelograms on two sides of a triangle, extended the external parallels to intersection, connected the included vertex of the triangle and the intersection point, used the direction and length of that segment to construct a parallelogram adjacent to the third side of the triangle, and proved that the sum of the areas of the first two parallelograms is equal to the area of the third parallelogram (Williams, Thomas 578-9). Section five of book five of the Collection discusses regular solids with equal surfaces and their varying sizes (Heath 395). Pappus's conjecture was that the solid with the most faces is the greatest (Heath 396). He proved this using the pyramid, the cube, the octahedron, the dodecahedron, and the icosahedron of equal surfaces. Pappus noted that some of the other major Greek geometers had already worked out the proof of this conjecture using the analytical method, but that he would give a method of his own by synthetical deduction (Heath 395). Using 56 propositions about the perpendiculars from the center of a circumscribing sphere to a face of the solids, Pappus proved that if the dodecahedron and the icosahedron were inscribed in the same sphere, the same small circle in the sphere would circumscribe both the pentagon of the dodecahedron and the triangle of the icosahedron (Heath 396). He went on to show that the cube is greater than the pyramid, the octahedron is greater than the cube, and so on (Heath 396). One of Pappus's biggest contributions to geometry is Pappus's Theorem, which states, "If the vertices of a hexagon lie alternately on two lines, then the meets of opposite sides are collinear" ("Pappus"). When put another way, "If A, B and C are three distinct points on one line and if A', B' and C' are three different distinct points on a second line, then the intersections of AC' and CA', AB' and BA', and BC' and CB' are collinear" (Smart 26), Pappus's Theorem spawns the Geometry of Pappus. This is a finite geometry consisting of exactly nine points and nine lines. The pairs of points making up the intersecting lines are interchangeable (Bogomolny 2). Also, Pappus's Theorem is self-dual (Bogomolny 2), meaning that if the words "point" and "line" were interchanged in the theorem, it would still hold true. Thanks to the duality principle, any theorem proved for Pappus's geometry is also true for the dual geometry. According to Pappus, the purpose of the Collection was to explain the propositions established using geometrical methods by the ancient Greek mathematicians in a shorter and easier to understand from, and to introduce some useful theorems he himself discovered (Heath 429). Thanks to Pappus and his Collection, the world better understands theorems, propositions, and conjectures made by geometers such as Euclid, Archimedes and Ptolemy. And Pappus's Theorem and the resulting geometry helped to bring the idea of duality to life so it could be applied to axioms from other geometries.

Definition and Examples of Deductive Arguments

Definition and Examples of Deductive Arguments Deduction is a method of reasoning from the general to the specific. Also called deductive reasoning and  top-down logic. In a deductive argument, a conclusion follows necessarily from the stated premises. (Contrast with induction.) In logic, a deductive argument is called a syllogism. In rhetoric, the equivalent of the syllogism is the enthymeme.​ Etymology From Latin, leading Examples and Observations The fundamental property of a deductively valid argument is this: If all of its premises are true, then its conclusion must be true also because the claim asserted by its conclusion already has been stated in its premises, although usually only implicitly.Scientific Deduction and Rhetorical DeductionFor Aristotle, scientific deduction differs in kind from its  rhetorical  counterpart. True, both are conducted according to the laws of thought. But rhetorical deduction is  inferior for two reasons: it starts with uncertain premises, and it is enthymematic: it generally relies on audience presuppositions to supply missing premises and conclusions. Because conclusions cannot be more certain than their premises and because any argument is deficient in rigor that relies on audience participation for its completion, rhetorical deductions can yield at best only plausible conclusions. . . .Syllogisms and EnthymemesVery rarely in literary argument do reasoners make use of the complete sy llogism, except to render perfectly apparent the premises from which the conclusion is deduced, or to show some fault in reasoning. Deductive arguments take various forms. One premise, or even the conclusion, may not be expressed if obvious enough to be taken for granted; in this case, the syllogism is called an enthymeme. One of the premises may be conditional, which gives the hypothetical syllogism. A syllogistic argument may be involved in a statement with its reasons, or with its inferences, or may be diffused throughout an extended discussion. To argue effectively, with clearness and cogency, the reasoner must have his deductive framework clearly in mind at every point of his discussion, and keep it before the reader or hearer.

The Abecedarian Project and Early Childhood Intervention Essay

The Abecedarian Project and Early Childhood Intervention - Essay Example I feel that there is a difference between the results found in this controlled study project study and what is found in the regular preschool. The reason behind my argument is unlike the regular preschool, for this controlled study there was an early intervention which determined academic improvement as compared to the regular preschool where intervention was done during the school-age. The controlled study provided long-term support where the children were provided with year-round, full-time childcare unlike the other regular preschool children who had minimal support or in some cases none. The children of the controlled study received individualized attention where there was a high ratio of staff to the student in every stage of the program which most of the regular preschool children lack (Karoly 78). The controlled study children were provided with better privileges than the regular preschool children (Karoly 113). Among these privileges were free diapers, transportation, food, a cademic and social improvement activities. The regular preschool children lacked some of these privileges and thus creating the difference. Another difference was that the children from the controlled study were brought up in better living conditions thus improving their developmental growth, socially, physically and education wise. For the regular preschool children they grew up in poverty thus had development differences. The controlled study children had a more positive head start in life, unlike preschool children.

Home work - Assignment Example he major financial issue raised in this article is the increasing cost of health insurance and the high profits earned by health insurers despite the reduction in the availment of medical care by most Americans (Abelson, 2011). One other issue is whether health insurance companies should already be charging high premiums because they expect a rise in the pay outs they will be giving in the future. A legal issue conveyed in the article is about the effect of the health care law on the high premiums presently being charged by health insurers. Is it legal for these companies to be increasing charges already to cover the federal laws’ provisions? It is the legal responsibility of a doctor to maintain confidentiality of the medical records of his patient. It is also his legal duty to practice his profession within the scope of his training and capabilities. A doctor must work within the guidelines of the employer’s health care contract and the government’s health care legislations. Insurance premiums are rising even when patients’ demands for care are decreasing because the insurance companies are preparing themselves from any sudden rise in demand when the economy improves and the people have more money to spend on their health needs (Abelson, 2011). Some observers are also saying that the insurance companies are already preparing for the full enforcement of the health care law in 2014 where they expect to earn less when coverage will be more accommodating (Abelson, 2011). If patients are postponing preventive tests, later on it might affect the quality of their health. This is quite alarming because the possibility of curing some illnesses increase with early detection. In the long run, the amount they think they are saving from postponing preventive test may not even be enough to cure future diseases they may acquire. Delaying preventive tests can cost the patients more financially and will have a negative impact on their health. The likely

Figuring out the truth Essay Example for Free

Figuring out the truth Essay Everyone has been lied to, mistreated or even betrayed at some point in their life. That feeling is awful, but to be the person that did so wrong should feel even worse because of the pain they caused to someone else. The meaning of this quote to me is very relatable in a lot of ways, being right out of high school I know what its like to have been lied to and feeling like an idiot because you probably believed something that someone told you, you thought was the truth then ended up finding out it was all a lie. People will always find out the truth even if you don’t tell them straight up. So why do we lie? We all have done it and we know its not right but we continue to do it. Do we think that we will always get away with saying something that’s not the truth? Where is lying going to get you in life? It gets you no where, telling the truth may not be the easiest thing but it’s the right thing to do even if you have done wrong and think you should look like a good person and tell a lie to cover up what you had done but telling the truth is actually the right thing to do. People will get in trouble for telling the truth if the truth isn’t what they want to hear and they will also get in trouble for lying because it was the wrong thing to do. The truth may not always be the prettiest but it’s not as ugly as lying about something that someone is going to find out eventually. One day. In the quote Brudzinski mentions that â€Å"one day the truth will emerge†¦Ã¢â‚¬  one day someone is going to find out all the truth. One day someone is going to regret not telling the truth and having to deal with the consequences of what they lied about. Why not just face the truth and get it over with instead of living with the fact that you made someone feel better by telling a lie and knowing that when they found out you didn’t tell them what really was the truth they will feel the complete opposite of when they â€Å"thought† you told them the truth but was really all a lie. This quote to me means that people need to fess up to what they have done right in the beginning then waiting for the truth to come around and having to explain yourself for doing wrong. It relates to me a lot with my friends recently. You really get to know who your true friends are when someone gets caught in a lie. I know I have lied before to my friends to maybe get out of doing something that they all wanted to do and I now think back to that and I know that wasn’t the right thing to do and not just that but all because I didn’t want to do something that everyone else wanted to do seems so selfish. When it comes to lying theres more than not just telling the truth, you can loose friends and family because of something you said wasn’t true. How will someone ever trust you after they find out that you’ve lied to them? This quote relates mostly to middle school and high school girls. It’s the stage where everyone has to fit in so they try there best to do so and a lot of it comes with lies. Trying to fit into the popular crowd in middle school is not an easy task and no body wants to be left out. You have to have the name brand clothes, all of today’s electronics, and not to mention you have to get the boys to notice you. Girls try so hard to fit in now days, if you aren’t this skinny we cant be friends with you, if you don’t go to that concert everyone will think you’re poor. Girls are cruel to each other now days so teenage girls try their best to do what they can to have all the friends they can and lies are tossed around all the time so they can be more popular. Where are the lies getting these girls? All they will ever know is that its ok to be fake and have a mask. Lies turn people into someone there not. Be happy with what you have, you don’t need to throw out lies to just â€Å"fit in†, if someone doesn’t accept you the way you are you wouldn’t want to be friends with them anyways. I believe finding out the truth is the hardest part after being lied to. The fact that someone had to come up with a story to get out of telling the truth is sad. It doesn’t hurt one person but it hurts both people, the one who told the lie and the one who got told the lie. It makes the person who had to come up with a story to avoid the truth look like a betrayer. Don’t be that person, stand up and face the truth, you’re going to have to at some point so why make up a false statement when you could tell the true one. This quote is simply about finding out the truth. Why do people lie? Most people think they will get by most of the time but in the end someone always finds out the truth which is like a corpse in the water, someone is going to find that body eventually and the story will all come together. Why lie when someone is going to find out the truth at some point. â€Å"One day the truth will emerge, like a corpse in the water. † Wieslaw Brudzinski.

Goldratts The Goal Essay -- Goldratt Goal Bottleneck Essays

Goldratt's "The Goal" â€Å"The Goal† by Goldratt is a book about the Theory of Constraints, TOC. It is about the behavior of manufacturing facilities. It deals with bottlenecks that are the manufacturing constraints and the variability that creates them. The book states that a manufacturing organization cannot run at 100% and that you cannot balance the assembly line. It seems that your efforts for efficiency must be focused on the worst bottleneck. The loss caused by a bottleneck is a loss for the entire system. Focusing on improving the throughput of the bottleneck increases the flow for the entire manufacturing line. If there is a bottleneck, then all other areas are capable of excess capacity. Don’t try to improve non-bottlenecks, as it is a waste of time and effort. The TOC integrates into Total Quality Management, TQM, except for one main theory. TQM supports continuous improvement of the system while the TOC does not support continuous improvement of every process. The TOC says that we must focus on the constraint. Q: What is the Theory of Constraints about? A: Developed by Dr. Eliyahu M. Goldratt, TOC states that any system has at least one constraint. Otherwise, it would be generating an infinite amount of output. Bearing this in mind, TOC is easily explained through use of the "chain" analogy - "a chain is only as strong as its weakest link." If we look upon our organization as a chain, where each department is a "link" in the chain, what constrains our organization from achieving its goal? Only through addressing the weakest link, the constraint, can substantial improvements be made. In other words, if the constraint dictates the pace of an organization's ability to achieve it's goal, it makes sense that addressing the constraint will allow the organization to achieve a substantial rate of throughput faster. There are five steps in applying TOC: 1.  Ã‚  Ã‚  Ã‚  Ã‚  Identify the system's constraints. Of necessity this included prioritization so that just the ones that really limit system progress toward the goal. 2.  Ã‚  Ã‚  Ã‚  Ã‚  Decide how to exploit the system's constraints. Once we have decided how to manage the constraints within the system, how about the majority of the resources that are not constraints? The answer is that we manage them so that they just provide what is needed to match the output of the constrained resources. We NEVER let them supply mo... ...achine was running and an operator on your line was to set it up if it went down, you could take your break at your convenience. A few months went by and new coaches were hired. They decided they wanted to closely monitor the operator to see when they took their breaks and for how long. The decision was made to stop the machines when you go on your break and/or lunch. The new coach obviously wanted to make a good impression and bring something new to the table. They changed our staggered breaks to scheduled breaks. The results after a few weeks showed production was down and efficiency was at a record low. It showed machines were not running at full capacity for a tour. Immediately their superiors decided we would go back to the staggered lunches and breaks. The downtime was then reduced and our departmental efficiency went up. They realized it was not as important to monitor the person, as it was to have the machine running. Now I know this does not stand up to the problems Alex and his staff faced with UniCo but this is what I face everyday. I found a case study that was used at the TOC World 2000 Seminar in St. Paul MN last year. I thought I would include it for your enjoyment

City Life vs Country Life

Today the city life is more and more stressful, by the minute, however the people who were born and raised in the country are coming to the city, but which is better? It depend on the likes and necessities of that particular person, he or she may only be in the city because they can find much more entertainment and facilities. Meanwhile the country?s advantage consists on the calm and relaxation that it offers to us. For this and more reasons these two places are completely different. To start off the difference between these two places is the nature. In the country everything is natural; there are hardly any buildings, up to now making it difficult to destroy the ecosystem and pollute the nice luxurious air. In the city on the other hand, it is very difficult to see a lot if any trees or a forest area, a fact is that we can see a lot of buildings, smudge, and pollutions. As a result, natural areas are reduced, something that really affects our ecosystem, in the most atrocious way. I’d take the country in this point any day and twice on Sunday. Another difference is the distance between places. In the country people are used to walking to go from place to place over long distance, which is good because it is a great healthy benefit, also in the country traffic jams do not exist. So if you wanted to drive anywhere it’ll take you 30 minutes instead of the 3 hours in the city. Because of the 5:00 rush hour in the city, in which in my most humble opinion is not fun to be in trust me I’ve had my fair share of them. Again the country takes the cake. The next difference is the lifestyle. In the country, people can have a healthier lifestyle. Because of the farming, and there is a very calm place and people have more relaxing situations. However in the city people are always in a hurry rushing from place to place. Nobody has any time to do anything anymore. Nevertheless any of these options to live can be the best according to people's plans; also it depends on the ideas and jobs of everyone. If they want to relax and let pain just melt away the country is the way to go. But if they prefer a busier schedule and more variety on entertainment, the city no matter how messed up it is the thing for you.

Law, Ethics & Corp. Governance Essay

1. Describe what steps you would take to address the following scenario involving skills, competence, and abilities: The employee seems to be unable to learn the computer applications that are basic to her job responsibilities, but, consistently â€Å"tells† her boss that she is â€Å"a good worker and a genius† and that he does not â€Å"appreciate her†. Even after a few months of training and support, she is unable to use the computer tools to be productive and efficient in completing the required tasks. This can be a difficult situation for an employer to make because many employers try to see the positive and have faith in all their employees. If this situation took place within my company, I would continue to observe the employees attitude as well as dedication. Many times, employees are not capable of performing certain tasks, however, with a humble mindset, it is possible to work with them and guide them while working. This specific employee seems to have a self-assured mindset that she is not doing anything wrong. Instead of opening up and allowing her boss to assist her, she becomes arrogant. I would go a different route and have a professional come and train her from another company to see if that would help. If this specific assistance does not help, I will have to write the employee up to warn her that she must submit to the work load within a certain time frame. I do not believe this is being harsh to the employee. If she is hired to do a specific task and cannot get the task accomplished, then she is incapable of doing the work. I will be able to provide a written statement and have her terminated. Employers cannot waste time on employees who talk about their capabilities, yet not perform them. According to â€Å"Law and Ethics in the Business Environment† Chapter 2, she is able to voice her opinion publically in court, however, she must have written proof to back her up whys he should not be terminated. 2. Describe what steps you would take to address the following scenario involving management, behavior, and performance: The employee tends to burst into a rage when criticized and is frequently late to work as noticed by her boss and other staff members. When her boss attempts to address her behavioral issues and the company late policy, the employee’s response is that she â€Å"knows her rights and what to do† if she is wrongfully discharged. She also says she took a business law class in undergrad that taught her â€Å"everything she needs to know about exceptions to the employment-at-will doctrine and wrongful discharge in violation of public policy†. I would provide counsel and verbal warning to the employee. It is important to get all of the facts and bring that person into your office without making a big scene. Being honest and upfront about the tardiness and improper behavior will get much respect from the employee and show firm leadership. I will discuss what has been taken place and how important it is to have the whole department working on one accord. I will also discuss that their tardiness is not fair to the other employees. I would take the time to ask if there is anything wrong, or if there is something happening in the workplace or personal life that is causing what is perceived as â€Å"a person with a bad attitude who is unhappy at work. I believe listening and showing empathy will let the employee know you care about their well-being but yet, still mean business. There may be some personal issues that they just need to get off of their chest. If I get a sarcastic response from them, then I must be strong, but not attacking, and let them know that the behavior shown is not acceptable and needs to improve. I would be sure that I am focusing on the problem, not the person. In situations like these, staying calm and let them do the talking will show the humility in you as a leader. In situations like these, I would point out their strengths, and try to first focus on the good aspects of their performance rather than a perceived bad attitude. Documenting and date this conversation as a verbal warning to the employee, yet not making it a threat. This is not a written warning, but shows that you did talk to the person about difficult employee issues. The more the employer documents, the easier it will be to terminate if it gets to that point. The biggest mistake is to not document. Documentation and building a case is the proof that shows you talked to this employee many times but to no avail (Sheahan, 2012). 3. Describe what steps you would take to address the following scenario involving labor and laws: The employee takes a day off from work, without management consent, for her religious holiday observance that falls on a day that is during â€Å"tax season†. The day off occurred during an incredibly busy period for the company during which the employer had notified all employees they were not allowed to take off without prior management approval. Also, there is no labor union for accountants. However, she begins talking to her co-workers during lunch breaks and sometimes during regular work hours, encouraging them to organize and form a union to â€Å"protect ourselves†. This can be a difficult situation because it involves the employee’s religious rights. According to an Act in 1997, â€Å"GUIDELINES ON RELIGIOUS EXERCISE AND RELIGIOUS EXPRESSION IN THE FEDERAL WORKPLACE†, Agencies shall not discriminate against employees on the basis of religion, require religious participation or non-participation as a condition of employment, or permit religious harassment. And agencies shall accommodate employees’ exercise of their religion in the circumstances specified in these Guidelines. These requirements are but applications of the general principle that agencies shall treat all employees with the same respect and consideration, regardless of their religion. At the same time, employees are not to engage in religious acts with employees by forcing their beliefs and opinions on them. This can cause immediate termination. Regardless of religious observation day or not, an employee is not to take a work day off without employers permission. The employer has every right to terminate the employee. It is understandable to observe religious acts as an individual but there has to be communication between employee and employer. The employer has to make accommodations for that specific day. 4. Describe what steps you would take to address the following scenario involving policies and procedures: The employee’s supervisor consistently asks her out on dates; the employee initially refuses to go out on a date with her supervisor. The employee later discusses the issue with her girlfriend who encourages her to accept his offers. During her new employee orientation, the employee was informed of the company policy which prevented employees from dating their supervisor and was given an employee handbook with the written policy. The employee and her supervisor later begin having a consensual relationship. Based from the research according to Saalfeld Griggs PC Publications, a supervisor dating an employee is prohibited within many companies. Although romantic relationships in the workplace are common, employers have legitimate reasons for concern about employee dating. The biggest fear is a sexual harassment lawsuit arising from either a supervisor who has a habit of asking subordinates out on dates; an employee who files a lawsuit after a consensual relationship goes sour; or the perception of co-workers that a supervisor is playing favorites with his or her â€Å"significant other. A policy that prohibits a supervisor from dating a subordinate must also describe the penalty imposed if the policy is violated. Men often hold more senior positions in a company, therefore, a policy that always penalizes the subordinate (e.g. by requiring termination or transfer) may create sexual discrimination liability. When enforcing a â€Å"no dating† policy, the employer must be careful to penalize both sexes equally. An employer who selectively enforces the policy, or enforces it more harshly against one sex compared to the other, may be liable for sexual discrimination. In a consensual relationship between a supervisor and a subordinate, the subordinate often is the recipient of preferential treatment. Employees have asserted claims for sexual harassment based on the theory that they can’t receive the same benefits because they are not â€Å"sleeping with the boss.† The policy is in writing and both the employer and employee decided to go against this policy. If one or the other is not able to transfer to another department, they must suffer the consequences of being released from the company. Reference Page: 1. Halbert, T., & Ingulli, E. (2012).

You can watch crystal growth under a microscope or let the crystals grow overnight for larger crystals. Directions Suspend a piece of copper wire in 0.1M silver nitrate in a test tube. If you coil the wire you will get high surface area and more visible growth.Place the tube in a darkened location. Try to avoid high-traffic (high-vibration) areas.Crystals should be visible to the naked eye on the copper wire after about an hour, but larger crystals and noticeable blue coloration of liquid will occur overnight.ORPlace a drop of mercury in a test tube and add 5-10 ml 0.1M silver nitrate.Allow the tube to stand undisturbed in a dark location for 1-2 days. Crystals will grow on the surface of the mercury. Tips It is easy to watch crystals form on a copper wire under a microscope. The heat of the microscope light will cause crystals to form very quickly.AÂ  displacement reaction is responsible for crystal formation: 2Ag Cu → Cu2 2Ag Materials Needed 0.1M Silver NitrateTest TubeCopper Wire or Mercury

Failure of Real-Time Online Facility Assignment

Failure of Real-Time Online Facility - Assignment Example These major changes and other significant measures require a complete devotion and perfect dedication from the management, administrative department and particularly the Information Technology department to stabilize the performance of our online school and take our pride from good to best in the online school (Linda 1995). Everybody was appreciating and praising the performance of our online school before the advancement of technology introduced by our one of the closest competitor in the online school sector. Ever since this improvement has been presented by the competing firm, a steep decline has been observed in the size and magnitude of the market share of our online school. Profits have stuck somewhere, lowering from 8% to 5.5%. Faculty turnover ratio has increased substantially from 4% per annum to somewhat 16% annum. Increased customer complaints received more than 6% from the previous period. Things are pointing a major problem in our processes and demanding a significant solution to overcome that problem. What actually is that problem? How is it showing its effects and implications on the management and other departments of the business? What are the possible remedies to rescue? What would be the consequences of this operation clean sweep? Who is going to gain and who is going to lose? These all critical questions will be probed in the following discussion. Since the inception, the main focus of our online school has remained on providing the education to our students in a virtually â€Å"real-time† online environment. Students always liked and valued this methodology of teaching as it provided them the core benefits that they always needed. This methodology provided the students with an opportunity to interact with their tutors and mentors live on our online web portal, group forum and other live chat and discussion platforms. This helped the students in tackling with their study curriculum related issues with their tutors and share their problems in an online streaming session conducted via our live web portal.

Genetics assignment two - Essay Example sive alleles of each of these genes (a,b,c and d) produce abnormal enzymes that cannot catalyze a reaction in the biosynthetic pathway for seed pigment. The pathway is shown below: 2. In the Australian Shepherd, Hereditary Cataracts is an autosomal dominant disorder that results in abnormal clouding of the lenses of the eye. In some Aussies, heterozygous for Hereditary Cataracts, the disease is not always expressed. Based on this information, answer the following questions: b. Several alleles are responsible for Hereditary Cataract formation. When present, some alleles result in very rapid cataract growth, whereas; other alleles result in very slow cataract growth. What terminology best describes the behavior of these various alleles? 3. In the oriental fruit fly (Bactrocera dorsalis), a number of genes determine eye color. A fly with wild-type eyes (red) is crossed to fly with yellow eyes. All the F1 flies from this cross have wild-type eyes. When the F1 from the cross are interbred (selfed), 450 of the progeny have wild-type eyes, 150 have amethyst eyes (a bright sparkling blue color) and 200 have yellow eyes. 4. The Scots Dumpy, a type of chicken from Scotland, can exhibit short-leg length and normal-leg length phenotypes. A breeder crosses two normal-legged Scots Dumpy, and finds that all of the F1 are normal-legged. The breeder repeats the cross and observes the same result. However, when the same breeder crosses a normal-legged fowl with a short-legged fowl,  ½ of the offspring are short-legged and  ½ of the offspring are normal-legged. Finally, following a third cross between two short-legged Scots Dumpy fowl, the breeder observes the following results among 200 offspring counted: 5. Fruit flies homozygous for the recessive allele, sc-, have bright red eyes. Fruit flies homozygous for the recessive allele, br-, have brownish purple eyes. Fruit flies homozygous recessive for both alleles have white eyes. Fruit flies that possess the sc+ and
