Mitosis/Meiosis Comparison

Miranda Presnell 7th period

Meiosis

a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.

Meiosis

  • Takes place in the germ cells.
  • Occurs only in Sexually reproducing organisms .
  • There are Two cell divisions, the first and the second meiotic divisions.
  • Interphase precedes only in meiosis I, It does not occur prior to meiosis II.
  • DNA replication takes place during interphase I but not Interphase II.

Mitosis

  • Takes place in the somatic cells of the body.
  • Occurs in both sexually as well as asexually reproducing organisms.
  • The Cells Divide only once
  • Interphase occurs prior to each division
  • DNA replication takes place during interphase I.

How are the alike ?

  • They both involve division of a cell.
  • The processes of division are the same. (anaphase, Metaphase, etc.).
  • Replication of chromosomes occurs before division.
  • Same number of chromosomes at first divisions.
  • Two sets of chromosomes for both are enclosed by the nuclear envelope
