The differences between Mitosis and meiosis are listed in the table given below:
|
Mitosis
|
Meiosis
|
1.
|
Mitosis takes place continuously in the somatic cells of the body
|
Meiosis occurs in germ cells during gametogenesis
|
2.
|
Cells divides only once
|
Two cell divisions take place- First and Second meiotic divisions
|
3.
|
Prophase is comparatively simple, shorter duration and includes no substage
|
Prophase is relatively complex, longer duration and includes six sub-stages: Preleptotene, Leptotene, Zygotene, Pachytene, Diplotene and Diakinesis
|
4.
|
There is no synapsis
|
Synapsis of homologous chromosomes occur during prophase
|
5.
|
Chiasma formation ( crossing over) does not take place
|
Chiasma formation (crossing over) takes place
|
6.
|
Duplication of chromosomes takes place in early prophase
|
Duplication/splitting of chromosomes takes place in late prophase
|
7.
|
Chromatids occur in the form of dyads
|
Chromatids of two homologous chromosomes occur as tetrads
|
8.
|
Spindle fibres disappear completely in telophase
|
Spindle fibres do not disappear completely in telophase I
|
9.
|
Genetic constitution of daughter cells is identical to that of the parental cells
|
Genetic constitution of daughter cells differs from the parent cell.
|
10.
|
Occurs in both asexually and sexually reproducing organisms
|
Occurs in only sexually reproducing organisms
