I would like to believe that the father of the lone Gerudo male is the former lone Gerudo male himself. You'd think that the leader would be a "pure blood" when all of the others are mixed (so I guess that would make the mother "mixed" too..... but they still look the exact same I guess). If we're going to get any Gerudo backstory at all, which I highly doubt because Nintendo is stupid, I'd expect the former Gerudo male before Ganondorf to be the leader. And I don't think he'd be evil either, seeing as I believe in the theory that it was just the evil spirit Ganon that possessed Ganondorf.
