Suppose That Pigmentation in Rabbits Is Controlled by Two Genes

question 4

Essay

Suppose that pigmentation in rabbits is controlled by two genes (E and H).Each gene exhibits complete dominance,and the relationships between genotypes and phenotypes are listed below:
$$\begin{array} { l l } \text { Genotype } & \text { Phenotype } \\E /- ; H /- & \text { albino } \\e / e ; H / - & \text { brown } \\E / - ; h / h & \text { albino } \\e / e ; h / h & \text { albino }\end{array}$$
a)Two brown parents produce an albino baby rabbit.What are the genotypes of each of the parents and that of the kit (baby rabbit)?
b)What phenotypic ratio would be expected among the progeny of an intercross between dihybrid rabbits?
c)In a litter of five baby rabbits from the above cross,what is the probability that all five of the baby rabbits will be albino?
