K locus dominant black
Dominant black is a gene colour gene in dogs that overrules all the agouti alleles, producing a dog with no tan markings no matter which agouti genotype they carry. It is part of the K locus. This coat colour gene is found in many different dog breeds.
The dominant black gene does not affect the coat colour of dogs that are genetically red or cream. The black pigment it produces can also be modified to brown and/or dilute if these genes are also present. Dominant black does not prevent white markings.
We report results from this test as either KB or n, where an n could be either tan (which can be referred to as Ky) or brindle (which can be referred to as Kbr).
