The AY allele is dominant to both A and a.
The homozygous genotype (AYAY ) results in lethality before birth.
heterozygous genotypes (AYA or AYa) result in yellow fur color, regardless of which alleles are present for the B/b gene.
(This effect exhibited by the AY allele is known as epistasis--when the expression of one gene masks the expression of a
Suppose you mate two mice with the genotypes AYaBb x AYaBb . Considering only the live-born offspring, what
would be the expected frequency of mice with yellow fur? (For help getting started, see Hint 1.)
