Its because of genetics. Females have two chromosomes which are X and X, but a Males chromosomes are X and Y. So while the baby is being formed, thegender will bedetermined bythe chromosomes they receive. The baby will always receive an X from the mom, but if also receives an X from the dad, then the baby will be a girl (two X's= Female). Now if the baby receives a Y chromosome from the dad then it will be a boy (X and Y= Male)
