A spermatozoon joins an ovum to form a zygote. A zygote is a single cell, with a complete set of chromosomes , that normally develops into an embryo. Sperm cells contribute approximately half of the nuclear genetic information to the diploid offspring excluding, in most cases, mitochondrial DNA. In mammals, the sex of the offspring is determined by the sperm cell: a spermatozoon bearing a X chromosome will lead to a female XX offspring, while one bearing a Y chromosome will lead to a male XY offspring.
