Difference between mitosis and meiosis
SN. | Point of distinction | Mitosis | Meiosis |
1. | Occurrence | It occurs in all somatic cells or vegetative cells (except gamate formation) | It occurs in germ or reproductive cells. |
2. | Number of cells produces | A diploid/haploid cell produces two identical diploid/haploid cells, so called equational division. | A diploid cell produces four haploid cells. Hence, it is called reduction division. |
3. | Phases or stages | Mitosis completes in 4 stages-prophase, metaphase, anaphase and telophase. | Meiosis is divided into Meiosis-I and Meiosis-II and each has 4 stages
|
4. | Prophase | Duration of Prophase is short and not divided into sub-phases. | Duration of Prophase-I is long and divided into 5 sub-phases-leptotene, zygotene, pachytene, diplotene and dikinesis |
5. | Metaphase | Chromosome occurs as dyads in metaphase. | Chromosome occurs as tetrads in metaphase-I |
6. | Metaphasic plate | Centromeres forms single metaphasic plate | Centromeres forms two metaphasic plate |
7. | Homologous chromosome | Absent | Present |
8. | Synapsis and crossing over | Absent | Occurs |
9. | Anaphase | During anaphase chromosomes are having single chromatids | During anaphase homologous chromosomes occurs and have two chromatids |
10. | Types of cells | It occurs in both haploid and diploid cell. | It only occurs in diploid cell. |
11. | Mode of reproduction | Asexual | Sexual |
