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 types of colored patches generally appear in a merle coat: brown ...
Dogs display wide variation in coat type, density, length, color, and composition. 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.
Tricolor can also refer to a dog whose coat is patched, usually two colors (such as black and tan) on a white background. Blue merle tricolor Shetland Sheepdog: Red merle Catahoula Leopard Dogs: Merle: Marbled coat with darker patches and spots of the specified color. Merle is referred to as "Dapple" in Dachshunds. Tuxedo Lab mix. Tuxedo Collie mix
When a dog has wild-type alleles at all three genes, it will have a yellow coat. When the dog has a loss-of-function allele at MC1R, it will have a yellow coat regardless of the genes it carries on the other two genes. Only a dominant black allele at CBD103 will produce a black coat color in dogs possessing wild-type alleles at MC1R and Agouti. [8]

The first possibility is a side effect of the merle gene. Merle dilutes random parts of the paint, including the eyes and nose. This dilution results in a bluish iris, and merle dogs often have blue, walled, or split eyes due to random pigment loss. The higher the dilution of the merle coat, the more likely they are to have blue eyes.
A Stanford University School of Medicine study published in Science in October, 2007 found the genetics that explain coat colors in other mammals such as in horse coats and in cat coats, did not apply to dogs. [1] The project took samples from 38 different breeds to find the gene (a beta defensin gene) responsible for dog coat color. One ...
This color also has alternate names such as Liliac or Silver. When Liver is combined with Merle, the eumelanin (black) pigment is further diluted in random patches. This usually creates a light reddish-gray dog with dark brown patches. This color is often called "Red Merle" even though that is misleading.
