During the past few years, Labrador Retriever has earned its name and becomes one of the most popular dog breeds in many countries.
Currently there are three recognized colors of a Lab, black, chocolate, and yellow. These three colors are a result from interplay between genes that direct production and expression of the two pigments, pheomelanin, and eumelanin.
Those two genes create the three recognized colors, and the third gene affects the range of coloration in Yellow Labrador.
Nowadays, due to many mixing of the Lab breed, many Labradors have a mixture of the three colors, black, brown, and yellow.
So if you are thinking of adopting a Labrador, and you see a Lab with a mixture of colors, it doesn’t mean that it is not a purebred.
