1. In our classroom for most traits, were there more students with dominant or recessive phenotype? 2. Was there an instance where there were more students with dominant phenotype but more recessive alleles? (q larger than p?) 3. How is this possible?

10. The recessive allele that causes Ellis-van Creveld syndrome when homozygous has a frequency of about 0.07 in the Amish population of Pennsylvania, although its frequency is only about 0.001 in the general population. How many persons out of one thousand in the Amish population would be expected to have the disease? a. How many out of one million in the general population would be expected to have the disease? 19 19

1. Describe scaling relationships. What is isometry, hypoallometry, hyperallometry? Which traits scale to the power of 1, 2, 3?

1. What is the genotype for a cat who is heterozygous for both traits? Options: LlMm, LLMM, Llmm, LlMM, llmm, llMm, llMM 2. What is the genotype for a cat who is homozygous recessive for both traits? Options: llmm, LLMM, LLmm, LLMm, llMM, llMm 3. How many would have long hair? Options: 0,4,8,12,16 4. How many would have long hair and be all white? Options: 0,4,8,12,16 5. How many would have short hair and have some color (not all white)? Options: 0,4,8,12,16 6. How many would be all white? Options: 0,4,8,12,16

1. In a wild strain of tomato plants, the phenotypic variance for tomato weight is 3.2g². In another strain of highly inbred tomatoes raised under same environmental conditions, the phenotypic variance is 2.2 g². With regard to wild strain a. What is VG b. What is h₂² C. Assuming that all of the genetic variance is additive what is h²

7. While Squidward's family boasts about being a purebred line for dominant light blue skin color, they are also purebred for a less distinguished trait: the recessive trait of baldness. Lack of hair causes Squidward some self-esteem issues that he does not want his children to face. He would like to ensure that his offspring have hair AND with his blue skin color. What traits should he look for in a bride? A. Must she have hair? Explain. Squidward Traits: Skin Color B. Must she be blue? Explain. Blue = B, Green = b Hair Hair = H, Bald =h C. Squidward has found a potential bride prospect with the green squid Octavia. While Octavia has does not. Determine the chances of their child being blue and having hair. hair, her father Squidward's Genotype Octavia's Genotype = D. Use the genotypes in above to complete the Punnett square below and then answer the questions. E. Answer these questions based on your Punnett square. For which traits, if any, is it possible for their offspring to be…

8. Ability to taste PTC (phenyl thiocarbamide), a bitter chemical found in some vegetables, depends on carrying at least one dominant allele, T, for the taster trait. Non-tasters are homozygous for the recessive allele (t). Another trait, albinism, is inherited as a simple recessive in which normal pigmentation is dominant. An albino man who is a taster and has a mother who is a nontaster marries a normally-pigmented woman who is a nontaster and whose father is an albino taster. (a) What are the genotypes of the man and his wife? (b) What types of children might this couple expect? MI 900 9. In pigeons, the checkered pattern depends on a dominant allele C and plain on the recessive allele b. recessive allele c. Red color is controlled by a dominant allele B and brown by the (a) Diagram a cross between homozygous checkered red and plain brown birds. Summarize the expected F₁ and F₂ results. (b) A checkered brown female mated with a plain red male to produce 2 checkered red, parents. 2…
