D locus dilute d (common type)
Dilution is the colour gene that dilutes brown to a silver or fawn colour, and black to a blue or slate colur. Dilution is a recessive trait. This means that dogs can silently carry the dilute gene, without being dilute themselves. Dogs like this - dilute carriers - can potentially produce dilute puppies.
The dilute d test is for the common form of the dilution gene found in many different dog breeds. It can create the dilute coat colours by itself or in combination with the rarer dilute d2 gene.
