. You are studying cats and coat colour. You have pure-breeding black female cats with normal toes and you cross them to pure-breeding orange male cats with extra toes. You get F1 progeny that all have extra toes. The males are all black and the females are all tortoiseshell (with black and orange patches of fur).

A. (4 points) Explain the F1 phenotypes by assigning symbols to the genes and alleles in question, showing the parental and F1 genotypes. Use correct genetic notation.

B. Suppose you allowed the F1 to interbreed. What would be the expected phenotypic ratios among the progeny? Explain, using the genotypes of the F2 as part of your explanation (6 points)

3.Although there are likely more, there are five major genes that interact to control coat colour in mice. These are: A, B, C, D and S. The A allele produces a phenotype called agouti, which caused by a band of yellow colour on a dark hair shaft. The result is a brindled or salt and pepper appearance. The non-agouti (controlled by the a allele) lacks the yellow band and is a solid black. The B gene controls the colour of...

You are doing a genetics experiment with fruit flies. In your first cross, you cross two true-breeding flies (P generation). The female parent is brown and wingless and the male parent is black with normal wings. All of the flies in the F1 generation are brown and have normal wings. In the following questions, please indicate the alleles associated with dominant phenotypes by uppercase letters and alleles associated with recessive phenotypes by lowercase letters. Assume the genes are not found...
