S Locus

This allele is associated with Piebald, Parti, Landseer, or Random White Spotting among several breeds where these patterns are observed. The inheritance and expression can vary depending on the breed. For example, the gene is most often recessive in nature, however in some breeds such as Collie, Great Dane, Italian Greyhound, Shetland Sheepdog, Boxer, and Bull Terrier, an animal having 1 copy of the piebald allele can exhibit some limited piebald expression.

Test Results:

Possible Genotypes:
NN – 2 copies of the non-piebald allele
N/S – 1 copy of the non-piebald allele and 1 copy of the piebald allele
S/S – 2 copies of the piebald allele
