If you look at coat color inheritance in labs, chocolate is a double recessive. So it is harder to get dogs which will produce chocolates than yellows or blacks. I figure anytime you have to breed to a more difficult target, you will end up collecting several traits common in "overbred" dogs.

So... are you saying there is a fart gene?
