Degrees of gameness don't really matter. The question was merely, if gameness ( any degree) is genetic, can mishandling of a dog decrease the full potential a dog was born with.

I do not think one can ruin the genetic pre-disposition to be game but I think one could ruin a dog before game becomes a question, or better said, one can ruin a dog before gameness should be in question.
That counts for dogs who not start or enjoy (again) after they were "ruined" for sure. But what if they do and their gameness will come into question?

What i hear allot is: "The dog chose the easy way out once, next time he'll do it again"

I hear the description of a cur dog while its the owner who put a dog in the ring who was not ready to be in it.
