In the case of Labradors, the black and chocolate colors are determined by dominant and recessive alleles at one gene locus. The black coat color (B) is dominant to chocolate (b). Therefore, a puppy will only be chocolate if each parent contributes a chocolate allele (b) giving the puppy a genotype of “bb”.
