Meiosis, on the other hand, is a division of a germ cell involving two fissions of the nucleus and giving rise to four gametes, or sex cells, each possessing half the number of chromosomes of the original cell.
Mitosis is used by single celled organisms to reproduce; it is also used for the organic growth of tissues, fibers, and mibranes. Meiosis is useful for sexual reproduction of organisms. I hope this can help greatly</span>
