Title: Re: Briefly explain the contribution of the woman's ovum and the man's sperm in dete Post by: bio_man on Sep 10, 2012 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.
