Labrador Retrievers are a popular dog breed in many countries. There are three recognised colours, black, chocolate, and yellow, [1] that result from the interplay among genes that direct production and expression of two pigments, eumelanin (brown or black pigment) and pheomelanin (yellow to red pigment), in the fur and skin of the dog.
The gene at the B locus is known as tyrosinase related protein 1 (TYRP1). This gene affects the color of the eumelanin pigment produced, making it either black or brown. TYRP1 is an enzyme involved in the synthesis of eumela

Liver dilution can also be combined with other genes that dilute a dog's coat. The D locus dilutes black pigment to a blue-grey color usually called Blue. It is a recessive trait like Liver. When a dog has both Liver and Blue dilution, it will appear to be a light, warm-gray color known as Isabella. This is the color of Weimaraners. This color ...

Domestic dogs exhibit diverse coat colours and patterns.In many mammals, different colour patterns are the result of the regulation of the Agouti gene, which can cause hair follicles to switch from making black or brown pigments to yellow or nearly white pigments.
