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?
