There’s no better way to establish a personal take on the nature vs. nurture debate than to breed your own kids. I recommend at least one of each.
True, it’s a highly subjective experiment, but you get to monitor the results 24/7!
One interesting result from our family lab (say it like the British: lab-ohr-a-tohry) is The DaddyFactory Law of Gender Predetermination which shall henceforth be used to reinforce all gender stereotypes that suggest that girls will be girls and boys… well, this sentence is long enough already.

When SUBJECT B (my son) was a toddler, he had no idea that there was an armoire in his bedroom and he had no interest in what might have been hiding inside. But when SUBJECT G (his sister) was no more than 18 months, she was opening that thing and rummaging through the little dresses she discovered with a vigor previously reserved for my wife’s bosom. [Why, you ask, did we have dresses in an armoire in a boy's room? To trick him, of course. All part of the gender experiment. Controls and such. Science, man, Science.]
Girl = Girl = Fashionista
Keep all options open, but let those girls be girls. And when they want to do your hair, just say “Yes.”
