Answer:
The differences between mitosis and meiosis :
Mitosis
- Occurs in somatic cells
- Chromosome or DNA replication is followed by one nuclear division, thereby maintaining the amount of DNA and the number of chromosomes per cell constantly from generation to generation.
- Two daughter nuclei are produced from a single parental nucleus.
- The prophase is comparatively shorter duration and does not have any subgroups.
- All chromosomes behave independently of each other.
- There is no crossing-over or exchange of chromatids between homologous chromosomes
Meiosis
- Occurs in reproductive cells
- Chromosome or DNA replication is followed by two nuclear divisions. Thus, each of the daughter cells contains half as many chromosomes and half as much DNA as its parent cell.
- Four daughter nuclei are produced from a single parental nucleus.
- Prophase is a longer duration. It is differentiated into subgroups.
- Homologous chromosomes get paired together.
- Crossing-over or exchange of parts of chromatid between homologous chromosomes is a rule.

MEOSIS:
Meiosis is a type of cell division that results in the formation of four daughter cells each with half the number of chromosomes as the parent cell.
MITOSIS:
Mitosis is the type of cell division that results in the formation of two daughter cells each with the same number and kind of chromosomes as the parent cell.
