WebWhat is Meiosis? Meiosis is a type of cell division that occurs in the sex cells. In this article, explore what it is, stages of meiosis and importance of meiosis in detail. During the event of meiosis, the chromosome count shrinks to half (cell biology).
WebSignificance of Meiosis. Having genetically different offspring can be advantageous for natural selection. Meiosis has several mechanisms that increase the genetic diversity of gametes produced. Both crossing over and independent assortment (random orientation) result in different combinations of alleles in gametes.
