We are taking a summer break from December 21 to January. You can still place orders now and while we are on break. If we we receive but don't finish testing your samples before Christmas they will be at the top of our list when we re-open in January. Samples that arrive during the break will be stored carefully for testing in January.
Thanks for all the testing you've sent us this year, and have a wonderful summer!
K locus dominant black
Summary
This test determines if your dog carries one or two copies of the dominant black gene (called KB). The name 'dominant black' is a bit misleading, since this gene essentially gets rid of tan pigment from a dog's coat rather than making fur black.
If your dog has at least one copy of the dominant black gene, they will not have any tan markings no matter which agouti genotype they carry.
Please note that other genes play a role in determining the final coat colour and pattern. For instance, the black pigment produced can also be modified to brown and/or dilute if these genes are also present. And the dominant black gene does not prevent white markings, or affect the coat colour of dogs that are genetically cream or red.
We report results from this test as either KB or n, where an n could be allow tan (which can be referred to as Ky) or brindle (which can be referred to as Kbr).
