 DIFFERENCES BETWEEN MITOSIS AND MEIOSIS  

 EVENTS

 MITOSIS

 MEIOSIS

 Occurrence

 In all the body cells including germ cells.

 Only in the germ (reproductive) cells.

 Definition

 It is an equational division.

 It is a reductional division.

 Number of daughter cells

 Only two

 Four

 Prophase

 Involves relatively few changes.

 Involves a series of changes in chromosomes distinguished into 5 substages.

 Chromosomes

 Not visible in prophase.

 Visible in the leptotene stage of prophase - I

 Synapsis

 Does not occur.

 Occurs in zygotene of prophase-I.

 Crossing over

 Does not occur.

Occurs in pachytene stage of           prophase - I.

 Metaphase

 Chromosomes arrange along the equator.

 Chromosomes arrange equally on either side of the equator in metaphase-I.

 Centromeres in Anaphase

 Each centromere splits into two.

 Centromeres do not split in metaphase-l.

 Centrome- res in Metaphase

 Orient towards the equator while chromatids orient towards poles.

 Orient towards poles while chromatids orient towards the equator in metaphase-I.

 Telophase

 Results in the formation of two daughter nuclei having the same no. of chromosomes as that of parent cell.

 Telophase-II results in the formation of two daughter nuclei, each having half the no. of chromosomes as that of parent cell.

 Cytokine- sis

 Follows immediately after karyokinesis.

 May or may not occur at the end of first karyokinesis
