well tam, lol sex chromosomes decide what gender we are. girls have XX chromosomes and guys have XY sex chromosomes. you see we all start out as a girl, with one X chromosome. Then as we develop as babies, we either get another X chromosome or a Y chromosome. Since we all started with an X, we get all get nipples ;]
