In Mice, Black Color (B)is Dominant to White (B)

question 70

Essay

In mice, black color (B)is dominant to white (b). At a different locus, a dominant allele (A)produces a band of yellow just below the tip of each hair in mice with black fur. This gives a frosted appearance known as agouti. Expression of the recessive allele (a)results in a solid coat color. If mice that are heterozygous at both loci are crossed, what is the expected phenotypic ratio of their offspring?
