It seems that women have something called microchrondia (thanks spell check) that only pass from mom to daughter, not father to son. Ummmmmm....
That's mitochondria, and they are passed to male and female offspring equally from the mother. They are present in the egg, and the sperm doesn't have any.
They are the cells' powerplants and are not related to miscarriage or behavior.
Well isn't there something only passed from mom to daughter? I seem to remember some documentary about that being the way they trace migrations of races.
