In brief: See Below

Whether the fetus receives an x or y chromosome from the father. Y = girl x = boy.

Other way round: X = female. Y = male.

In brief: That is complicated

First, you may mean sex which is about the anatomy on a baby.
Whether they have a penis or a vagina. That is determined by the chromosomes of the sperm. Gender is whether a particular person feels male or female and how they express themselves. No one really knows how gender is determined but we seem to be born feeling like a boy or a girl.
