What's the truth about hybrid vigor and genetic diversity? We know inbreeding is bad. So it's it the case that breeding with a different race would increase the health of your offspring or is there a point at which you're going too far on the other direction? I'm Italian and Irish. At least I know for a fact my parents aren't related, but I'm still white. It's this not the best way to breed? I think im just trying to rationalize banging a hapa or a jap.
