Genetic research on wolves in Yellowstone National Park links coat color with reproductive success, disease resistance, and more territorial behavior.

Yellowstone National Park helps protect wolves as a species and provides a place for research opportunities for scientists. Genetics studies have found a link between coat color and certain survival traits of Gray Wolves. Despite the name, not all Gray Wolves are gray, some are black. According to the study black-coated wolves carry a gene called K-Locus. This gene has an immunity function in addition to coat color. For example, black Gray Wolves have a higher survival rate during distemper outbreaks. On the contrary, gray-coated wolves tend to have a higher reproductive rate, and a behavior trait that makes them more aggressive than black-coated wolves during territorial conflicts with other wolf packs.

Other wolf research in Yellowstone National Park includes:

  • How wolves improve an ecosystem through predation.
  • Behaviors like pack cooperation and care of offspring.
  • Territories and territorial defense.
  • Genetic studies to evaluate health & kinship between packs.
  • Genetic studies to identify connectivity between other Northern Rocky Mountain packs.
