Females are XX, whereas the males are XY. Therefore, a female will always contribute an X chromosome and a male will contribute either an X or a Y chromosome. If the male contributes an X, then the fetus will be a female because it will then have been XX. If the male contributes a Y chromosome, then the resulting fetus will have be XY and be a male.
