In the Yellowstone National Park they have somehow gotten black wolves in their park however they never had any wolves with black coats. Usually the black wolves are usually found throughout the rocky mountains in the U.S through Canada. The farther north you go the more white wolves you find which are Arctic wolves and by the central by the Great Lakes states you will find more gray wolves and very few black wolves. The things that determine black coat wolves such as camouflage, behaviors, finding mates, and thermoregulation. The genetics study that was conducted on the two breeding groups of wolves can only produce gray wolves. What created this black coat color in the wolf population is our own dogs. Domestic dogs around 7,000 years ago were first introduced to the wolf population when domestic dogs breed with wild wolves. They found this when conducting the genome experiment on the Yellowstone wolves, however they also found that it wasn’t just for colors. It also shows that black wolves do have a stronger immune system then regular wolves do. However there is a downside as well gray wolf genetics show that females have a higher success rate with their litter of pups then black coat wolves do. I found this article interesting because before I came to Stockton I remember when I was back at brookdale and they brought actual wolves in. One was 60% wolf and 40% German shepherd which the coat color was white, and the other one which did have a black was actually 90% wolf and 10% of something else I don’t think they really specified the other side. I find this interesting that man's best friend is what gave wolves another color to add to their populations. Not to mention years of repopulation the gene is still rare however it gets bigger due to the reintroduction into another population from breeding between them.
If anybody is interested he had a Facebook live video of his presentation:
