The Chromosomal Basis of Inheritance
... Half the sperm cells receive an X chromosome, and half receive a Y chromosome. Because of this, each conception has about a fifty-fifty chance of producing a particular sex. If a sperm cell bearing an X chromosome fertilizes an ovum, the resulting zygote is female (XX). If a sperm cell beari ...
