Question

difference between meiosis and mitosis.

Answer 1

mitosis-i) this type of division takes place in somatic cell.ii) two daughter cell are formed.iii) No.of chromosome remains diploid in daughter cell.iv) mitosis is necessary for growth and repair.v) crossing over does not take place.
meiosis- i) this type of division takes place in gametic cell.ii) four daughter cell are formed.iii) No.of chromosome becomes haploid in daughter cell. iv) meiosis is necessaryfor sexual reproduction.v) crossing over takes place.

Answer 2

Answer :-

The difference between meiosis and mitosis is as follows :-

• "Mitosis" takes place in the somatic cells only whereas, "Meiosis" takes place in the germinal cells only.

• In "Mitosis", the Prophase is simple and short whereas in "Meiosis", the Prophase is long with sub-stages.

• In "Mitosis", no exchange of parts between chromatids of a chromosome takes place whereas in "Meiosis", mutual exchange of parts between the chromatids of a chromosome takes place.

• In "Mitosis", no Chiasmata are formed whereas in "Meiosis", Chiasmata are formed.

• In "Mitosis", crossing over doesn't take place whereas in "Meiosis", crossing over takes place.

• The process of "Mitosis" gets completed in only one stage whereas, the process of "Meiosis", takes two stages to get completed.

• In "Mitosis", 2 daughters cells are produced whereas in "Meiosis", 4 daughter cells are produced.
