Meiosis is a type of sexual reproduction Meiosis is a type of sexual reproduction. A form of cell division that allows offspring to have the same number of chromosomes as their parent. This kind of cell division, which produces gametes (sex cell) containing half the number of chromosomes as ...
Cell Division: Mitosis vs. Meiosis Cell division increases the number of somatic (body) cells or produces the sex cells (gametes). Development/growth Repair injured cells Production of sperm or egg Karyokinesis is division of nucleus. Mitosis Results in two daughter cells Genetically identical to ...
