Ah, the Y Chromosome

Interesting how some people attribute so much by ways of intelligence to the lilliputian Y chromosome. That poor guy must be packed with all sorts of good shit... the math genes, abstract thinking, self-reliance, ability to be more than sort of a semi-autonomous incubator on legs... my goodness.

Except WAIT... the Y chromosome is almost entirely composed of second copies of genes needed in two copies also found on the X chromosome, with the majority of its length consisting of non-coding DNA*. There is essentially only one gene, the SRY gene, which is involved in the determination of masculinity and all it entails.

That means the difference between men and women is determined by one gene, and then what? The ENVIRONMENT, you say? What a naughty word. Surely how we are brought up has no influence on our behaviors or our psyche. This would be tantamount to saying that society influences how men and women feel they need to behave. Never, I say. I am programmed by my genes to want to shave my legs and wear dresses, as well as to be bad at chess. No conditioning or lack thereof has caused these behaviors. No siree.
