Details
The K locus, or Dominant Black, refers to testing for the K-locus. There are a number of factors for determining a dog's visible (phenotype) coat colour and pattern, as many genes are involved to create a dog's coat. Within the K locus options include: dominant black - where a dog has inherited at least one K gene, will be solid black, (Kk, KK), kk can show tan markings, kbr - brindle, k - recessive non-black. Dominant black dominates the whole of the A locus, but it can be modified by other genes, such as liver, dilution, greying and merle. That black coat can then be changed to liver, blue, isabella or merle. The K locus plays a pivotal role in coat color. This locus is a relative newcomer in our understanding of canine color, and includes traits formerly attributed by some to other genes.
