![]() ![]() brown eumelanin is present in hair follicles. These include the extension locus, which determines whether or not melanocytes move to a certain area of skin agouti locus, which determines if black hairs are produced instead of brown (in this case it’s an inhibitor) and finally the MC-IRS gene, which tells how much red/yellow pheomelanin vs. Wolf coat color is dependent on three genes that direct pigment growth. Here, the gray females have the advantage. The study on wolves in Yellowstone park showed how heterogynous black males had the highest survival rates, but this is different for females. The homozygous black wolves also did very poorly in terms of fighting disease. The study shows how wolves prefer to mate with heterozygous black wolves, and not homozygous black wolves. The gene for a black coat is dominant, meaning if a wolf has one black and one grey gene, they’d have a black coat. ![]() Homozygous means the wolf has two of the same color genes, while heterozygous means they have two different. The Yellowstone population is about 55% homozygous gray, 42% heterozygous black, and 3% homozygous black. The theory isn’t complete, but one theory is that the gene that impacts coat color also impacts how bacteria or viruses bind to cellular receptorsĭan Stahler realized that the split between gray and black wolves in Yellowstone park wasn’t a coincidence, but rather a natural selection to achieve the highest possible survival rates. One study, the Yellowstone Wolf Project, suggests that wolves with different colors have different survival rates, as well as a better chance of staying healthy.

Yellow WolvesĪ few select species of wolves have a yellowish, golden, brown coat color. Most red wolves are kept in captivity to avoid the extinction of the species. They will often have a mix of red and brown colors. Only about 0,0001% of wild wolves have this color. The red wolf ( Canis Rufus) is the rarest of all wolf colors. īlack wolves can be seen in all regions where gray wolves live, from Asia to North America. They’re also found in packs of red wolves. It’s believed that these wolves got their black color genes from domestic dogs due to wolf-dog hybrids.Īside from their coat color, they’re exactly like gray wolves. Blackīlack wolves are also a subspecies of gray wolves and are often seen among gray wolves. This species is a subspecies of the gray wolf, which is why they will often have a bit of gray color on their back. They’re found in regions such as Canada and Antarctica. The white wolf is often seen in areas with a lot of snow, as it helps them blend in with their surroundings. They will rarely be completely white, though they’re much lighter in color than the gray wolf. White wolves, known as the Arctic wolf, have a light-colored fur coat. Brownīrown is a dominant color in wolves and therefore occurs more frequently than most other colors.īrown wolf coats can also be quite dark or lighter depending on their habitat and sun exposure, ranging from dark brown to a lighter tan color. Their back will typically be darker than their abdomen. Gray wolves usually have a mostly gray fur coat with white, black, or brown sections throughout. This is because gray wolf habitat ranges from forests, mountains, plains…all throughout different climates. It’s estimated that there are between 200,000-250,000 gray wolves in the world. They can be found in Russia, North America, Europe, Northern Mexico, and everywhere in between. The gray wolf is the most abundant species of wolves in North America, as well as the world. The opposite is true for gray female wolves. Black males are estimated to have a higher survival rate than their gray counterparts. One interesting fact about wolves and their coat color is the relation between color and health. Most wolves will have a combination of these colors, such as gray wolves with spots of white and black. The most common wolf color is a mix of gray, brown, black, and white. The rarest wolf coloration is a red wolf, as this is the rarest species of wolves. This wolf lives in many regions, from North America to Europe. The gray wolf is the most common of all wolf species, which is why the color gray is most common in wolves. Most wolves’ coats will be a combination of these colors. These colors are different from species to species and will be one of the following: gray, black, white, brown, red, or variations of these. The color of wolves is the color of their coat. ![]()
