0. A zygote has two nuclei since it is formed combination of a sperm and egg.
The zygote is diploid, meaning that it contains two sets of chromosomes. Sex Chromosomes X-Y. The male gametes or sperm cells in humans and other mammals are heterogametic and contain one of two types of sex chromosomes. Sperm cells carry either an X or Y sex chromosome. Female gametes or eggs, however, contain only the X sex chromosome and are homogametic. The sperm cell determines the sex of an individual in this case. If a sperm cell containing an X chromosome fertilizes an egg, the resulting zygote will be XX or female.
