Difference between Mitosis and Meiosis

Mitosis Vs Meiosis

 

The major difference between mitosis and meiosis are-

 

Mitosis	Meiosis
1. Mitosis involves one cell division.	1. Meiosis involves two successive cell divisions.
2. It results in two diploid daughter cells.	2. It results in four daughter haploid cells.
3. In mitosis, a single cell is divided once to produce two identical daughter cells. ]	3. In meiosis, a single cell is divided twice to produce four daughter cells.
4. In daughter cells, the number of chromosomes remains the same as the parent cell.	4. In daughter cells, the number of chromosomes is halved from the parent cell.
5. Daughter cells are genetically identical.	5. Daughter cells are genetically unique/different.
6. Mitosis produces two identical daughter cells.	6. Meiosis produces four genetically different daughter cells.
7. Mode of reproduction Asexual reproduction.	7. Mode of reproduction Sexual reproduction.
8. Takes place in somatic cells (non-sex cells).	8. Takes Place in Germ Cells (sex cell).   Creates germ cells (eggs and sperm) only.
9. Mother cells can be either haploid or diploid cells.	9. Mother cells are always diploid cells.
10. Recombination or crossing over does not occur in mitosis.	10. Recombinationor crossing over of chromosomes occurs in prophase -I.   During crossing over chromatids of two homologous chromosomes are exchanged segments.
11. Tetrad formation does not occur in mitosis.	11. Tetrad formation occurs in meiosis.
12. No pairing of homologs occur in mitosis.	12. Pairing of homologs occurs in meiosis.
13. Chiasmata absent in mitosis.	13. Chiasmata observed during prophase I and metaphase I.
14. In Mitosis synapsis does not occur.	14. In meiosis, During prophase synapsis of homologous chromosomes occur.
15. Phases of mitosis includes- 1. Prophase, 2. Prometaphase, 3. Metaphase, 4. Anaphase, 5. Telophase.	15. Stages of mitosis includes-  Meiosis-l includes; Prophase I, Metaphase I, Anaphase I, Telophase I.   Meiosis-ll includes; Prophase II, Metaphase II, Anaphase II, and Telophase II.
16. Individual chromosomes line up on the cell’s equator during metaphase.	16. Pairs of chromosomes line up on the cell’s equator During metaphase-I.
17. During anaphase, sister chromatids are dragged to opposite ends of the cell.	17. During anaphase I, sister chromatids move together to the same cell spindle pole.   During anaphase II, sister chromatids are separated and pulled towards opposite ends of the cell.
18. Cytokinesis occurs in the Telophase phase.	18. Cytokinesis occurs in Telophase-I and in Telophase- II.
19. Purpose of mitosis is cellular reproduction and general growth and repair of the body.	19. Purpose of meiosis is to take part in the formation of gametes.
