Meiosis is a specialized form of cell division that produces reproductive cells, such as plant and fungal spores, sperm and egg cells. All cells originate from other cells. The primary mechanism by which this occurs is through cell division.
Unlike the bodyâs other cells, the cells in the egg and sperm â called gametes or sex cells â possess only one chromosome. Gametes are produced by meiosis cell division, which results in the divided cells having half the number of chromosomes as the parent, or progenitor, cells. In the case of humans, this means that parent cells have two chromosomes and gametes have one. During fertilization, gametes from the sperm combine with gametes from the egg to form a zygote. The zygote contains two sets of 23 chromosomes, for the required 46.
