I'm not so sure. I think it'd be an interesting study if done
properly, but really I know a few people whose parents are alcoholic
and they themselves tend to be very for alcohol or very anti-alcohol.
I don't know a single person in the middle in this category. The
anti-alcohol ones don't want to become like their parents, and the
pro-alcohol ones are pretty comfortable with it. I think both these
actions are behavioural. (Don't know anyone allergic to alcohol.)
I'm also not sure if intelligence (even if it's a genetic trait) is
also a good trait to have, in terms of reproductive success (personal
observation is that the intelligent (considered conventionally) people
I know don't tend to reproduce a lot or at all).
I'd say if there were genes for people against abortion, then it might
be a good one. <-:
