Meiosis

MEIOSIS

  • Meiosis occurs in eukaryotic life cycles involving sexual reproduction.
  • During meiosis, the genome of a diploid germ cell undergoes two rounds of division, resulting in four haploid daughter cells.
  • Each of the resulting daughter cells has one half of the number of chromosomes as the parent cell.
  • This reduction is accomplished by two successive nuclear divisions, as opposed to the one division found in mitosis.
  • The two stages of meiosis are Meiosis I and Meiosis II called Reductional Division and Equational Division respectively. ( Click here to view the picture )
  • Before a dividing cell enters meiosis, it undergoes a period of growth called Interphase.

  • In animals, meiosis used to produces the gametes: sperms and eggs.
