In mitosis, the end product is two cells: the original parent cell and a new, genetically identical daughter cell. Meiosis is more complex and goes through additional phases to create four genetically different haploid cells which then have the potential to combine and form a new, genetically diverse diploid offspring.
In animals, meiosis results directly in the formation of gametesâthe reproductive cells, egg and sperm. The successful union of an egg and a sperm is called fertilization, and the resulting cell is called a zygote. The zygote contains genetic material donated from both parents, and is genetically distinct from either.
