The sex of a baby is determined by the chromosomes in the sperm that fertilizes the egg. A sperm carries either an X or a Y chromosome, while the egg always carries an X chromosome. If the sperm carries an X chromosome, the resulting XX combination will be a girl. If the sperm carries a Y chromosome, the resulting XY combination will be a boy.
