Genetically:  

the sex chromosomes are different

(XX for women, XY for men)

Physiologically (how the body works):

Evolutionary psychology is the study of how our behavior and mind have changed in ways that have helped us adapt to our environment over time through the process of natural selection (nature allows those organisms that have adapted best to their environment to survive).

The father does.  

Since women are XX, they can only give their baby an X chromosome.  

Men are XY, so they can give either an X or a Y.  

If they give an X, the baby is a girl;

if they give a Y, the baby is a boy.

Human beings are less ruled by our genes than other animals, mainly because of our ability to learn.
