WebThis means there is a 50\% chance that a sperm has an X chromosome and and 50\% chance that a sperm has a Y chromosome. As females have two X chromosomes, all egg cells contain an X chromosome. All zygotes will have an X chromosome from the mother and either an X or Y chromosome from the father. This dictates the sex of the offspring. WebTo put that another way, meiosis in humans is a division process that takes us from a diploid cell—one with two sets of chromosomes—to haploid cells—ones with a single set of chromosomes.
