Women have no role in determination of baby's sex. However, there are some unproved theories about sex determination by woman.
Answer The sperm from the father can supply either an Xbearing or a Ybearing chromosome. The egg from the mother can only supply an Xbearing.

The mother's egg contains an X chromosome, and the father's sperm will contain either an X or Y chromosome.
