I agree, except for the caveat that we don't know exactly which DNA relates to what. In other words, we can't (yet) identify a gameness gene, an ability gene, etc.
In the end, a person has to go with
his eyes ... and
his own personal knowledge of "what he wants" ... and
which dogs in his pedigrees carry these traits ... if he is going to successfully make breedings that pass-on the torch he's trying to perpetuate.
Although I have no love for Pat Patrick, I do think his quote to me (back in 1993) was the best I have ever heard ... when I told him of the CompuPed Pedigree program Wildside Kennels started using ... Pat said,
"I don't need some fuckin' computer program to tell me that Bolio out-produced every other stud dog I had; all I had to do was start rolling his pups to see that."
