Men have a Y chromosome and an X chromosome, while women have two X chromosomes. So, a daughter (female offspring) has the X chromosome from the father and another one similar from the mother. On the other hand, the son (male offspring) would have one X chromosome from the mother and the Y chromosome from the father, so the answer is 100%.
