In labrador retriever dogs, coat color is determined by the interaction of two genes (pigment and deposition of pigment). this is called epistasis. coat color can be black (b) or brown (b) and deposition of pigment into the hair shaft is deposited (e) or not deposited (e). if a retriever has the genotype where they have _ _ ee, then they will have a yellow coat regardless of what color they inherit (e. g., bbee or bbee gives a yellow lab).
1. calculate the phenotypic ratios of a cross between a male and a female labrador retrievers that are both heterozygous for coat color and heterozygous for deposition of pigment.
what is the genotype of both the male and female parents?
what are the possible gametes of both the male and female parents?
what is the phenotypic ratio of the offspring?
