Dogs have a wide range of coat colors, patterns, textures and lengths. [1] Dog coat color is governed by how genes are passed from dogs to their puppies and how those genes are expressed in each dog. Dogs have about 19,000 genes in their genome [2] but only a handful affect the physical variations in their coats. Most genes come in pairs, one ...
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.

In later years, faster dogs were favored and a smaller Bullenbeisser was bred in Brabant, in northern Belgium. The Brabanter Bullenbeisser is generally accepted as being a direct ancestor of today's Boxer. [26] In 1894, three Germans, Friedrich Robert, Elard König, and R. Höpner, decided to stabilize the breed and put it on exhibition at a ...
One version produces yellow dogs, and a mutation produces black. All dog coat colors are modifications of black or yellow. [2] For example, the white in white miniature schnauzers is a cream color, not albinism (a genotype of e/e at MC1R.) Today, dogs exhibit a diverse array of fur coats, including dogs without fur, such as the Mexican Hairless ...
The Shikoku has 5 coat colors: red, red sesame, sesame, black sesame, & black with tan points. In addition, there is a cream colored coat that is rarely seen as it is not an accepted color in the breed.
