Question

Suppose that a mouse with black fur has both an allele for black fur and an allele for white fur (Bb). Based on this information, you can conclude that the dominant allele must be for
fur andthe recessive allele must be for
fur.

Answer 1

In this case, the mouse has the genotype Bb, where B represents the allele for black fur and b represents the allele for white fur. Since the mouse has black fur, we can conclude that the dominant allele must be for **black** fur and the recessive allele must be for **white** fur.
