explain the difference between meiosis and mitosis explain the difference between meiosis and mitosis
Answers
Answer: Meiosis and mitosis are nuclear division processes that occur during cell division.
Explanation: Mitosis has only one division of cells while meiosis has two. Mitosis has two daughter cells that are genetically identical to the parent cells. Meiosis has four daughter cells each of which has half the number of chromosomes.
Mitosis is the division of body cells and meiosis is the division of the sex cells.
Explanation:
Mitosis
1) This division takes place in somatic cells and as a result of this growth occurs.
2) Completed in one stage.
3) Prophase is smaller (when compared to prophase of Meiosis).
4) No crossing over takes place.
5) Synapsis does not take place at metaphase.
6) At metaphase, centromere is towards equatorial plate and ends of chromosomes towards poles. Centromere divides.
7) Chromatids are long and thin.
8) Cytokinesis follows karyokinesis.
Meiosis
1) It takes place in reproductive cells
2) Completed in two stages.
3) Prophase longer than prophase of mitosis and divided into five substages.
4) Crossing over takes place in which exchange of segments of chromatids occurs.
5) Synapsis between homologous chromosomes takes place (bivalent stage).
6) At metaphase I, the centromere is towards poles and ends of chromosomes towards equatorial plate. Centromere does not divide.
7) Chromatids are shorter and thick
8) After Telophase I, cytokinesis does not takes place always.
