E locus red/black


Some dogs have a creamy, golden or red coloured coat. Classic examples are yellow labrador retrievers, Golden retrievers, and Irish setters. The full range of red coat colours are also found in many other breeds and in mixed breed dogs.

The most common reason to test for red/black is to find out if your dog can produce red pups. Dogs with a single copy of red are indistinguishable from dogs with no copies of this gene, but can produce red puppies.

This test is for the common e1 allele and does not include e2 (found in Huskies) or e3 (found in cream Australian cattle dogs).

We report results from this test as either e1 or n, where an n could be E, Em, or a different red allele. Order the full E locus panel to get a more complete understanding which E locus genotypes are present in your dog.
