When the ovum and sperm meet at fertilization, the ovum provides that X chromosome, while the sperm provides either the X or the Y chromosome.  If the sperm contributes its X chromosome, the child will have an XX pairing and the offspring will be a girl.  If the sperm contributes its Y chromosome, the child will have an XY pairing and the offspring will be a boy.
