Dogs do not have red-sensing cones, so their sight is similar to that of someone with red-green color blindness, according to research by Jay Neitz, a professor of ophthalmology and a color vision ...
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 ...
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 ...
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 dogs in this breed occur in many different coat colors. A study that mapped the genes of Afghan Hounds and discussed the effect of genes on coat colour in the breed was published in the Journal of Heredity in 2010. [16] The Afghan Hound is tall, standing in height 61–74 cm (24–29 in) and weighing 20–27 kg (44–60 lb).
Dogs with a blend of Black and Red/Yellow fur can also look like they have brown areas. An easy way to tell if a dog is Liver or not is to look at their nose. Eumelanin (black) pigment colors a dog's nose, so a Liver dog will have a Liver colored nose. If the nose is black, the dog is not a liver. A pink nose has nothing to do with liver ...
