The Role of Genetics in Inherent Sex Differences

When we think about innate causation, there are certain traits that will emerge over time. Even though your DNA is pretty much fixed, the expression of those genes and the timing of the expression is also partly predetermined. And how much of the model of innate sex differences would we expect to be structural? How much would we expects to emerge in the brains of babies and how much would we expect it to be dormant until puberty or other hormonal events? That's a good question. I'm not really sure.
