Eventually all the dogs and all the redwolves, and gray wolves, and coyotes, and coydogs, and any other combination you want to find in that species will have mitochondrial DNA inherited from a single Ur-Wolf Mother!
(if they are allowed to breed around that will happen with any species).
Their non-mitochondrial DNA will, of course, be mixed and matched ~ and circulate forever ~ except for that in their y-chromosome. That, too, tends to become a dominant factor simply because of the math.
Just because some forests have swamp like characteristics or may be in the process of becoming a swamp doesn't mean that “swamp” and “forest” mean the same thing.
Anyway all this quibbling over your peculiar and misguided grouping of species doesn't change the point I made in regards to wolves and coyotes..........
Just because we have some 4% neanderthal ancestry and Africans do not - it doesn't mean that we are 96% different - that 4% ancestry may be distinctly neanderthal DNA - but it is still over 95% the same sequence as human DNA.
Humans, as a species, are not very different from each other in DNA. And mixing in 4% of something that is some 98% the same doesn't add up to a 4% difference - not using any math based in reality.
