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
