This biochemical pathway produces white, light grey or dark grey cats. A. What genetic interaction is shown? (10p) B. What would be the genotype of a true-breeding dark grey cat? (10p) C. What phenotypic ratio would you expect to see from an AaBb x AaBb cross? Include the information of genotypes and phenotypes. (20p) (For example: White (A_B_):  Light Grey (A_bb and aabb) = 3:1) D. From the progeny of the dihybrid cross in question C, you randomly pick one white male and one dark grey female to mate. What is the probability of getting a light grey kitten? (10p)

In Drosophila, males from a true-breeding stock with rosy eyes is mated to females from a true-breeding stock with ebony body color. (Wild-type flies are normally red eyed and brown bodied.) In the F1 generation, all the females are red eyed and brown bodied, and all the males are red eyed and ebony bodied. When the F1s are mated together, the 1000 F2 progeny are as follows: Progeny # F2 Phenotype 202 Red-eyed, brown-bodied females 198 Red-eyed, ebony-bodied females 120 Red-eyed, ebony bodied males 130 Rosy-eyed, brown-bodied males 80 Rosy-eyed, ebony bodied males 70 Red-eyed, brown-bodied males A. Write down the genotypes of P, F1 and F2 and diagram the crosses. Define your symbols (for example, R or r for rosy eyes; E or e for ebony body color) and chromosomes. (30p) B. Is there statistical evidence that the rosy eyes and ebony genes are linked? Apply proper test and discuss the result. (20p)
