How interesting. So using a statistically significant population sample, there will be no phenotypic differences between carriers of X versus Y chromosomes?
If so, science has progressed quite far in the last few years that I've been away.
There won't be much difference beyond reproductive roles and other physical traits, but the brain doesn't seem to be affected all that much, no.
Basically, there's no gene for being a programmer just as there's no gene for being a (good/bad) parent. Why would Nature bother to pre-compute/compile all possible states/outcomes? Better to compute/compile the essentials for a living species then let the rest be handled by history.
Evolution stops specializing when said specialization offers no beneficial adaptation sufficient for the metabolic cost. It's why the vast majority of living organisms have much simpler brains, body plans, and even reproductive strategies. Humans and other similar animals are rare little things in the vast ocean of simpler, more elegant mutations.
