Samples Accepted: Blood, Buccal Swabs
Locus Information: B-locus: b-allele
The B-locus codes for a color known as brown, chocolate, or liver, depending upon the breed. It is responsible for both hair and skin color. There are three recessive alleles that all result in the same color (bs, bd, be).
Test Information: This mutation test identifies the bs, bd, and be-alleles of the B-locus, all of which result in the brown color.
