A cat with seal (black) point coloration. Acromelanism or point coloration is a genetically determined, temperature-dependent pigmentation pattern, with full expression only occurring on legs, ears, tail, face and scrotum (in males). It is most recognized as the coloration of Siamese [1] and related breeds of cat, but can be found in dogs ...
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.
Dog coat genetics. 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. Dogs have about 19,000 genes in their genome ...
The coat of the domestic dog refers to the hair that covers its body. Dogs demonstrate a wide range of coat colors, patterns, textures, and lengths. As with other mammals, a dog's fur has many uses, including thermoregulation and protection from cuts or scratches; furthermore, a dog's coat plays an important role in the showing of purebred dogs.
Merle (dog coat) 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 ...
The exact name of the colorpoint pattern depends on the actual color. A few examples are seal points (dark brown to black), chocolate points (warm, lighter brown), blue points (gray), lilac or frost points (silvery gray-pink), red or flame points (orange), and tortie (tortoiseshell mottling) points.
The Colorpoint Shorthair is a variety of Siamese cat. The only major registries to recognise them are the Cat Fanciers' Association (CFA) and the World Cat Federation (WCF). This breed was established from breeding American Shorthairs with the Siamese to produce different point colors, beyond the four standard Siamese colors.
The French Bulldog ( French: Bouledogue Français) is a French breed of companion dog or toy dog. It appeared in Paris in the mid-nineteenth century, apparently the result of cross-breeding of Toy Bulldogs imported from England and local Parisian ratters. [ 3] It is commonly kept as a pet, and is among the most frequently registered dogs in a ...
