What she's saying here is that women weigh about 75-80% of what men do, but their brains are more than 75-80% the size of a man's brain, so the brain weight:body weight ratio is bigger for women.

It has been proven that there's a brain structural difference between the brains of male homosexuals and male heterosexuals. Since recent research on other topics has shown that structural differences in the brain can be caused by environmental effects, this means that the nature vs. nurture agruement, which many had hoped was laid to rest a decade ago, is still undecided.
