Yet are we not interested in passing all of those things down? Are those traits (brain function and physical features) not VITAL to the success of a performance dog, and actually what we base our choices of selection on?
It all ties in but the most precise we can get genetically is following the X and Y chromosomes. The reality is focusing on quality. To many skip this and say the genetics are there when the quality shows genetics. And yes I see how the skeletal, mental function(intelligence and will or gameness), reproduce, and sex that are sex linked genes go hand and hand with the autosomes of all ancestors passed. Speed in response of brains to cells are important but the outward response is only as fast as they are built to respond. You definitely can't take one without the other. One is still a better starting point in performing dogs.
