Question

What are the disturbance in mitosis and meosis

Answer 1

Below are the differences between Meiosis and Mitosis.

Mitosis -

1. One mother cell undergoes a single division, and gives rise to two daughter cells.
2. A haploid or diploid mother cell can undergo mitosis.
3. The ploidy of the daughter cell remains the same as that of the mother cell.
4. Synapsis and crossing over events do not occur during mitosis.
5. The genetic identity is retained after a mitotic division.
6. Centromeres spilt during anaphase, resulting in the separation of sister chromatids.
7. The major purpose is vegetative growth and asexual reproduction.

Meiosis-

1. One mother cell undergoes two successive divisions, and gives rise to four daughter cells.
2. Only a diploid mother cell can undergo meiosis.
3. Ploidy reduction occurs giving rise to haploid daughter cells.
4. Synapsis and crossing over between homologous chromosomes occurs during meiosis I.
5. Genetic variation is introduced during meiotic divisions.
6. Centromeres and the sister chromatid pairs remain intact during meiosis I, but separate during meiosis II.
7. The major purpose is to facilitate sexual reproduction through gametogenesis.
