I for the longest believed in petcentages, and inbreeding coeficients, but now that we have DNA, I don't see why you would use anything else. If you have the blueprint of what you want, why not try and replicate it? Here is another piece to add to the equation, most genes come in pairs. Although I don't have the DNA markers in front of me, what Jack says is possible. I have noticed in my own dogs different paired genes, for example, the dogs that I have with ultra finish in your throat high ability are super clean, they won't pee in the kennel, and they wait to deficate while I clean the kennels. The super intense crazy in the corner I'll Take what i can get, swap it out, front end, back end ,game as the night is long strain like Machobear and Machabear will shit all over the kennel, step in it, roll in it. Etc. What am trying to get Is that super smart finisher with the retard mentality, buy I think they are a completely different gene set
