Nicely written. But, DNA can tell the parentage of the animal. Which could lead to the study of the effects of inbreeding on the species. There are zoos that go to great lengths to prevent in breeding. Take for example the destruction of the healthy giraffe and its dissection in front of a group of kids and then they destroyed a p***e of healthy lions to prevent inbreeding. I do admire your thinking out of the box, and the exploration of genes and their placements in the helix; and even if we mapped the entire sequence, there is not way, at present, to replace specific genes and produce a dog that will not revert to instinctual nature of the wolf. If DNA is tracked then breeders can ensure that they are not interbreeding and therefor produce healthier specimens.

On the surface, your idea of checking the DNA sounds good. however, there are so many genes involved in temperament, not a single gene for any behavior in either man of dog. You would have to find all the genes for fear aggression, which are different from those which modify reactive to noise, territorial, food protective, toy hording aggression. The genes may be located in different areas for different breeds, so the crosses might have new locations, not like either parent. Studies to find the gene for primary lense luxation in terriers took years and thousands of dollars and it is only a single gene, no modifiers. Way too much of a task. then you have to add envirorment, epilepsy, brain tumors, diabetes as causes for aggression and you can see what an impossible task it really is. Suggestion for anyone buying a dog. go to a reliable breeder, handle their adult dogs, watch the dogs at dog shows and performance events, check the pedigrees, then train and socialize the dog well, feed it well and make sure that if you bought it as a house dog, not a working dog for livestock or hunting, it lives in the house with you. Make sure the breeder will help you any way they can, and get references from people who have purchased dogs from that person. A bargain dog seldom really is a bargain.
