Mitosis
Meiosis
Prophase is short and complete in one step
Prophase is long and complete in 5 sub phase which are leptotene, zygotene, pachytene, diplotene, diakinesis
Conserve chromosome number (2n)
Reduce the chromosome number (n)
No Synapsis occur to form bivalent during prophase
Synapsis occur to form bivalent during prophase I
No crossing over occur
Crossing over occur
No Chiasma
Have Chiasma
Contain of genetic material in daughter cell is identical as the parent cell
Contain of genetic  material not identical as the parent cell
Produce 2 daughter cell each (2n)
Produce 4 daughter cell each (n)
Cytokinesis occur once
Cytokinesis occur twice
Occur in the somatic cell
Occur in gonad cell
