Meiosis is a special type of cell division that only occurs in reproductive organs. Meiosis produces reproductive cells called gametes (eggs or sperm) which can form a zygote with chromosomes from both parents.
When cell division begins, the cells enter into either mitotic or meiotic phases. 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.
