Interestingly, when mothers learn the gender of their child, they talk to their daughters in the womb more than they talk to their sons. There was another study published recently that suggested that male and female babies might get subtly different breast milk. Basically it's extremely difficult to separate what's genes and what's environment/culture. Because a baby is treated differently, fed differently and spoken to differently, based on gender, their entire lives (and before, depending on your definition of life).
