Answer 1

Before we answer the question, here are some facts about mitosis and meiosis:

Mitosis :

1. It is a type of cell division of somatic cells(or the cells of the body) that results in two daughter cells ,which are diploid(2n) and are genetically identical.

2. This process replaces damaged cells.

3.It is a form of asexual reproduction where clones are produced.

4. A somatic cell divides once.

Meiosis:

1. It is a type of cell division of germ cells(or the sex cells) that results in the production of 4 haploid (n) daughter cells ,which are non-identical.

2. This process helps in the production of gametes(sperm ans ovum).

3. Crossing over takes place.Hence, there is evlolution of species.

4. A germ cell divides twice.
