Coat color in labrador retrievers is determined, in part, by two genes; B for black pigment (with bb being chocolate) and E for deposition of the pigment in the hairs (with ee resulting in a yellow lab). Cross a male chocolate lab that is heterozygous for pigment deposition with a female yellow lab heterozygous for black pigment. What pheotypic ratio do you get? Black, chocolate, yellow?
