Differences between mitosis and meiosis
|
Sl.No.
|
Mitosis
|
Meiosis
|
1.
|
An equation division separating sister chromatids.
|
A reduction division. The first stage is a reduction division which separates homologous chromosomes at first anaphase. Sister chromatids separate in an equational division at II anaphase.
|
2.
|
Only one division per cycle i.e. one cytoplasmic division (cytokinesis) per equational division.
|
Two divisions per cycle i.e. two cytoplasmic divisions, one following the reduction division and one following equation division.
|
3.
|
|
|
4.
|
Genetic exchange between homologous chromosomes does not occur.
|
Genetic exchange through chiasmata occurs between homologous chromosomes.
|
5.
|
Two daughter cells are produced.
|
Four daughter cells are produced.
|
6.
|
Genetic contents of daughter cells are identical.
|
Genetic contents of daughter cells are different. Centromere may be replica of either paternal or maternal centromeres in varying combinations.
|
7.
|
|
|
8.
|
Daughter cells are capable of undergoing additional mitotic divisions.
|
Daughter cells are not capable of undergoing another meiotic division although they may undergo mitotic division.
|
9.
|
Normally occurs in all somatic cells.
|
Occurs only in specialized germ cells.
|
10.
|
Begins at the zygote stage and continues through the life of the organism.
|
Occurs only after puberty, in higher organisms, but occurs in the zygote of algae and fungi.
