Cells in mitosis go through the PMAT stages once to produce diploid cells while cells in meiosis go through PMAT stages twice to produce haploid cells.
- Mitosis is a process by which a single cell divides to produce two daughter cells.
- In diploid (2n) organisms, somatic cells contain two copies of each homologous chromosome, thereby mitosis will produce two identical diploid cells.
- Mitosis consists of four phases: Prophase, Metaphase, Anaphase and Telophase.
- Meiosis is a process by which a single cell divides twice in order to produce four cells with half the original amount of chromosomes, it is for that reason that meiosis is recognized as a reductional division.
- Meiosis is divided into meiosis I and meiosis II.
- The phases of meiosis I include Interphase I, Prophase I, Metaphase I, Anaphase I, Telophase I, and cytokinesis; whereas the phases of meiosis II include Interphase II, Prophase II, Metaphase II, and Telophase II, and cytokinesis.
- During meiosis I, the chromosome or chromosomes duplicate their genetic information (S phase of the interphase I) and subsequently homologous chromosomes exchange genetic material during prophase I.
- In diploid organisms, these two daughter cells generated by meiosis I divide again in meiosis II in order to form haploid (n) gametes.
