Mitosis is a kind of cell division, where a parent cell splits into two identical daughter cells. Two cells are created during mitosis, but the original cell no longer exists so the total number will go up by one (or, if you're looking at multiple cells, the total number will double). The new cells have the same number of chromosomes as the original cell before it divided.
In gametogenesis, germinal cells multiply by mitosis and mature gametes are formed by meiosis
The daughter cells formed by meiosis are haploid, meaning they have only one set of chromosomes. In humans, the haploid number of chromosomes is 23.
Mitosis produces daughter cells with the same number of chromosomes as the original cell - so human cells produced by mitosis will have 46 chromosomes.
46 chromosomes or 23 pairs
Chromosomes have to be duplicated so that the same amount of DNA will be transferred into the new cells formed by mitosis. The new cells will be mutated if they do not duplicate.

During meiosis there is pairing between homologous chromosomes for exchange of chromatin material by crossing over and these chromosomes get separated in first stage of meiotic division, thus half of the chromosomes separate at each pole; the second stage of meiosis is more or less similar to mitotic division. At the end of meiosis 4 daughter nuclei are formed whereas in mitosis only 2 daughter nuclei are formed without reduction in the number of chromosomes.
It is beneficial in the replication of DNA. During this period of Mitosis two copies of each chromosome are produced.

Chromosomes are composed of two chromatids during the prophase and metaphase of mitosis. The chromosomes of formed in prophase and line up in metaphase.
there is no reduction of chromosome number.
there is no reduction of chromosome number.
