some of the studies you will see is hundrreds of years of genetic interpitations ...thats not gonna effect what we do in short term ....most people will be lucky to breed 5 generations of dogs in there lifetime ... most of us start our breeding programs years after we start hunting ...
One of the members on here that used to roll pits said that he'd had a puppy come out of his dogs that was colored differently than anything he's seen in his dogs. Said he traced the color back many generations in the dogs pedigree. If color can pop up like that, why not other traits ?
