The cоаt cоlоr in Lаbrаdor Retrievers is determined by two genes that are epistatic. Let the letters B and E represent these two genes. Each gene comes with two alleles. The B allele is dominant to the b allele, and the E allele is dominant to the e allele. To have black coat color, a dog must carry at least one dominant allele of each gene (the B and E alleles). Brown dogs lack the B allele (so they are homozygous for the b allele) and carry at least one dominant E allele. Homozygosity for the e allele results in yellow dogs, and it does not matter if yellow dogs have the B or b allele. When a black dog (BbEe) is crossed to a yellow dog (Bbee), what would be the expected ratio of coat color in their offspring?
