| Feature | Mitosis | Meiosis |
|---|---|---|
| Number of Divisions | One (equational division) | Two (reductional division followed by equational division) |
| Chromosome Number | Daughter cells are diploid (2n), identical to the parent cell | Daughter cells are haploid (n), half the chromosome number of the parent cell |
| Genetic Variation | No genetic variation; daughter cells are genetically identical to each other and the parent cell | Genetic variation is introduced through processes like crossing over and independent assortment |
| Purpose | Growth, repair, and asexual reproduction | Production of gametes (sperm and eggs) for sexual reproduction |
| Location | Occurs in somatic (body) cells | Occurs in germ (reproductive) cells |
| Stages Involved | Prophase, Metaphase, Anaphase, Telophase | Meiosis I: Prophase I, Metaphase I, Anaphase I, Telophase I; Meiosis II: Prophase II, Metaphase II, Anaphase II, Telophase II |
| Crossing Over | Does not occur | Occurs during Prophase I of Meiosis I, leading to genetic recombination |
| Synapsis of Homologous Chromosomes | Does not occur | Occurs during Prophase I of Meiosis I, forming tetrads |
| Outcome | Two genetically identical diploid daughter cells | Four genetically diverse haploid daughter cells |
| Function in Organism | Maintains chromosome number and supports asexual reproduction | Reduces chromosome number by half and introduces genetic diversity for sexual reproduction |
