This is a great question, but I don't have the time right now to answer it fully.

Gameness, like any other genetic trait, is merely POTENTIAL.

For example, a man may have the genetic potential to be a great runner, but that doesn't mean he will realize his potential for running

That man can either maximize his potential, or minimize his potential, by the choices he makes (how he eats, the environment he keeps around him, the shape he keeps himself in, etc.) So, just because he has the potential to run with the best in the world does NOT mean he is going to grow up to be a great runner ... only HIS CHOICES IN LIFE will determine that.

The same is true for a man's genetic ability to fight, his genetic intelligence, etc. The genetically intelligent man, for example, may do drugs and ruin his mind, he may not care enough to apply himself, etc. Or he may surround himself with bright minds, actively push himself, and achieve great scholastic recognition, etc.

The same with whole teams of people (football, baseball, basketball, etc.). This is where GREAT COACHING can make the difference between whether that team gets itself together and realizes its potential ... or not ... by great coaching (or lousy coaching).

And these same principles apply to these dogs ... but f***ing idiot owners cannot understand this. Idiot-dogmen always want to put everything on their dogs. If the dog isn't good, despite all the stupid things the idiot-owner has done NOT to help his dog be its best, the idiot-owner will blame the dog and say "only genetics" matter ... because the idiot-owner is too effin stupid to realize that genetic ability is ONLY POTENTIAL. And it is really frustrating to try to make stupid people realize how stupid they are.

The truth is whether or not that any dog's genetic potential is ever realized is ENTIRELY dependent on the choices the owner makes with his dog ... and good dogmen realize this fact and make it their business to make wise choices ... while the people who can't see the reality of this are always the stupidest of dogmen who make incredibly stupid decisions with their dogs
