Work Step by Step

The process of meiosis forms gametes, which are the mature sex cells. Gametes only have half the number of chromosomes as regular body cells. When a male and female gamete meet, they unite to form a cell that then has the full complement of chromosomes. The combination of DNA from two different individuals gives rise to offspring that are genetically different from its parents. Meiosis does not occur in all eukaryotes and only happens in cells that give rise to gametes called germ cells. Multicellular organisms grow and are able to repair damaged parts through the process of mitosis and cytoplasmic division, not meiosis.
