I was having a conversation with my wife, and we were discussing what causes the coat color of wolves to occasionally turn black. I told her that I thought it was a recessive trait and that in regions with more timber the darker color variation is a more favorable camo and natural selection favors the darker coloration. I thought I remembered hearing or reading about that. But then I did a little online research, and to my surprise I was finding many different conflicting answers. Some websites seem to suggest that the darker coat was actually a dominant trait. I found several websites that talked about a possible hypothesis that the black coat color is the result of wolves hybridizing with dogs thousands of years ago when people were crossing the bering straits land bridge. Anyhow, I thought I would post this to see if anyone had any clear answers or any insight into this mystery. What are your thoughts? Opinions?
