Meiosis The process of meiosis produces gametes or sex cells. While some parts of this cell division process are similar to the asexual cell division process of mitosis, there are several key differences.Meiosis produces gametes, while mitosis produces other cell types.The process of meiosis halves the chromosome number from the original parent cell in the four cells it forms. It does this by having two cell divisions forming four cells, where mitosis has only one cell division forming two cells.eiosis The process of meiosis produces gametes or sex cells.

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.
