Question

Write the differences between mitosis and meiosis.

Answer 1

Mitosis	Meiosis
1) This division takes place in somatic cells and as a result of this division growth occurs.	1) This takes place usually in reproductive cells and as a result of this character one generation pass into the other.
2) Completed in one stage.	2) Completed in two stages.
3) Prophase is smaller (as compared to prophase of Meiosis).	3) Prophase longer than prophase of mitosis and divided into five substages.
4) No crossing over takes place.	4) Crossing over takes place in which exchange of segments of chromatids occurs.
5) Synapsis does not take place at metaphase.	5) Synapsis between homologous chromosomes takes place (bivalent stage).
6) At metaphase, centromere is towards equatorial plate and ends of chromosomes towards poles. Centromere divides.	6) At metaphase I, the centromere is towards poles and ends of chromosomes towards equatorial plate. Centromere does not divide.
7) Chromatids are long and thin.	7) Chromatids are shorter and thick
8) Cytokinesis follows karyokinesis.	8) After Telophase I, cytokinesis does not takes place always (may occur).
