I really don't think that the prevalence of geniuses or mentally retarded among any social group has any significant effect on the overall distribution of power. You are speaking of people who are, by definition, outliers.
But even more theoretically, I don't see your point, though. History has proven beyond a doubt that society can and does change in rather extreme ways. In terms of changes to the power distribution in society, we are still far from hitting any biological limitations (and when we do, we often find technological solutions to them). So just because there are some biological limitations we should stop way short of them?
And we can take it further. Suppose (this is not the case, but suppose) that some large population is biologically significantly stupider than other groups (they're not idiots, just far from smart), and as a result, that group is constantly subservient to other groups, and has far less power to advance its interests. Don't you think we should actively help them? I mean, people can't fly, yet we've gone to great lengths to overcome that biological barrier through technology. We also go to great lengths (though that depends also on who suffers, but never mind) to overcome physical medical conditions. Shouldn't we also make some effort to fight social problems, or should we say, "let nature run its course" even though we never do that for anything else?
Finally -- and I'll repeat that because it's a relevant historical fact -- for centuries people (men and sometimes women, too) honestly believed -- they were certain, really -- that women are too stupid to be doctors and lawyers (although they put it gently with phrases like, "their wisdom lies elsewhere"). Then they said that regardless of intelligence, no one would put their life in the hands of a woman (or a black) doctor. But guess what? They were wrong and we got used to it. So while this is not a very scientific argument, history shows that -- so far -- if you base your arguments on what you believe are biological limitations or the persistence of social customs, you'd be on the wrong side of history.
