In mice, black fur (B) is dominant to white (b). At a different locus, a dominat 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.
A. If mice that are heterozygous at both loci are crossed, what is the expected genotypic ratio of their offspring?
B –A– : B–aa : bbA– : bbaa
Express your answer as four whole numbers separated by colons (for example, 4:3:2:1).
B. What is the expected phenotypic ratio of their offspring?
agouti: black: white
Express your answer as three whole numbers separated by colons (for example, 4:3:1).
