1. Meiosis requires two nuclear divisions; mitosis requires only one nuclear division.

2. Meiosis produces four daughter nuclei and four daughter cells; mitosis produces only two.

3. The daughter cells produced by meiosis are haploid; the daughter cells produced by mitosis are diploid.

4. The daughter cells produced by meiosis are not genetically identical; the daughter cells produced by mitosis are genetically identical to each other and to the parental cell.

OCCURRENCES:

- In humans, meiosis occurs only in reproductive organs to produce gametes.

- Mitosis occurs in all tissues for growth and repair.

MEIOSIS I:

- PROPHASE I: homologous chromosomes pairs undergo crossing-over
- METAPHASE I: bivalents align at the metaphase plate
- ANAPHASE I: homologous chromosomes (with centromeres intact) separate and move to opposite poles; in mitosis at this stage, sister chromatids separate and move to opposite poles.

MEIOSIS II:
Events of meiosis II are the same stages as in mitosis. However, in meiosis II, the nuclei contain the haploid number of chromosomes.
