Dog Color Genetics Summary: Genes & Alleles Overview This page is a quick reference to show you the possible alleles at each locus. Summary A list of variants and genes affecting coat colors and patterns in dogs: B locus The B locus determines if a dog has black or brown eumelanin. B: Black Eumelanin b *: Brown Eumelanin.
Dog Breeder Pro is a web-based software solution for dog breeders, with a range of useful features to help you keep track of pedigrees, waiting lists, test results and more. It also features a new advanced colour and coat genetics calculator that I've helped to design, so you can get detailed predictions for litters before you breed. Dogs have approximately 3 billion pairs of DNA, but only eight of the dog's genes contribute to the coat color.
Allele pairs in genes are located at sites called loci on the chromosome, and these eight loci affect the color of dogs' fur. And with a sound knowledge of genetics, dominant vs recessive genes, mutations, and possible alleles, predicting the color of puppies is a statistical probability. From two pigments comes multiple variations in canine coat color.
Canine Coat Color and Type Background Mammals have two pigments that are the basis of hair color: eumelanin (black) and phaeomelanin (red or yellow). One of the genes involved in the production of these pigments in many species including dogs is Melanocortin 1 Receptor (MC1R) which is also known as the Extension locus. 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 qualities are governed by how genes are passed from dogs to their puppies and how those genes are expressed in each dog. Good Dog is on a mission to educate the public, support dog breeders, and promote canine health so we can give our dogs the world they deserve. by Dr.
Mikel Delgado, PhD There are several genes that contribute to your dog's outward appearance - but perhaps the most obvious are those related to your dog's coat color. Use our Dog Color Genetics Calculator to predict puppy coat colors based on parent genes. Fast, accurate dog Genetics results with 20+ loci covered for breeders.
Coat color - dogs Introduction to coat colour in dogs Coat colour is influenced by the production of the two main pigments eumelanin (brown to black pigment) and pheomelanin (light to brownish red pigment). In most mammals, the synthesis of eumelanin or pheomelanin is regulated by two key genes, MC1R (locus E) and ASIP (locus A). Understanding dog genetics isn't the easiest thing to do, we've tried to break it down to make it as simple as possible so you can easily learn!
