It's not "having" the gameness, per se, that makes inbred brood dogs valuable ... because many authentically-game dogs simply can't throw their own gameness into their pups ...
Rather, it is these dogs being inbred on great dogs, known to THROW--gameness (ability, etc.) that makes them valuable.
If a dog is inbred on a low-percentage producer, that can't throw anything, then his "being inbred" means nothing worthwhile.
However, if the dog is inbred on a HIGH percentage-producer, and himself is game dog and comes from a high-percentage litter, then that dog is actually worth MORE than 98% of most match dogs in the brood pen
If that's what you're selecting for, yes.
My breeding program has always been based on gameness and a head style ... and that is pretty much what my line has come to be known for ...
