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
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
