Question
What is mitosis in brief and how is the process happening in sexual reproduction

Solution
Mitosis is a type of cell division in which one cell (the mother) divides to produce two new cells (the daughters) that are genetically identical to itself. In the context of the cell cycle, mitosis is the part of the division process in which the DNA of the cell's nucleus is split into two equal sets of chromosomes.
In sexual reproduction, two reproductive cells called gametes fuse in the process of fertilization. In order to avoid the duplication of the chromosome number, gametes are formed through a special form of cell division, meiosis, which halves the number of chromosomes. Cells with a single set of chromosomes are haploid (n), in contrast to the somatic (body) cells, which are diploid (2n). The fusion of the gametes during fertilization restores the diploid chromosome number in the first cell of the new individual, the zygote.
In the human life cycle, haploid gametes produced during meiosis fuse to form a diploid zygote, which goes through the process of mitosis to grow into an adult human. When the adult human produces haploid gametes, the process can be repeated.
