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 second way blue eyes can appear is when a dog has a lot of white fur on the face. Since the white areas cannot produce any pigment, pigment from the eyes and nose may be lost as well. [68] The third way is when dogs are affected by albinism. [68] A different gene, unaffected by coat color, can make the eyes blue. However, this gene is rare.
It also interacts with Cream dilution to produce "pseudo-double" Cream dilutes with pale skin and blue or green eyes. Silver Dapple Gene lightens black hair, such as the mane and tail of a bay horse Mushroom (horse) describes an unknown and unmapped theorized dilution gene dilutes red pigment in body color to a pale beige color.

Chocolate Lab puppies from a reputable breeder typically cost between $2,000 and $6,000, depending on factors such as the breeder’s reputation, location, the puppy’s pedigree, and coat color.
Eye color is an inherited trait determined by multiple genes. [14] [15] These genes are sought by studying small changes in the genes themselves and in neighboring genes, called single-nucleotide polymorphisms or SNPs.
Heterochromia is a variation in coloration most often used to describe color differences of the iris, but can also be applied to color variation of hair [1] or skin. Heterochromia is determined by the production, delivery, and concentration of melanin (a pigment). It may be inherited, or caused by genetic mosaicism, chimerism, disease, or ...
Blue merle Border Collie puppy Red merle Australian Shepherd. Merle is a genetic pattern in a dog's coat and alleles of the PMEL gene. It results in different colors and patterns and can affect any coats. The allele creates mottled patches of color in a solid or piebald coat, blue or odd-colored eyes, and can affect skin pigment as well. Two ...
