So if it's not a cultural expectation, and it's not a coincidence, what else could it be but a genetic predisposition?

I think it's a matter of selective perception. I've never noticed any correlation between redheads and being moody, and on the whole I can't say the redheads I know are statistically moodier than the average person. I'd never even heard of that stereotype until reading this thread. But I can imagine that if you have some conception that redheads are "supposed" to be moody, you will remember the times they are moody and forget the times they act normal. Psychologists have proven that we tend to remember the things which reinforce our existing beliefs, and we tend to ignore the things which conflict with them.
