NEET BIOLOGY

Detailed explanation-1: -Sex cells are formed through a particular kind of cell division called meiosis. Unlike in normal cell division (mitosis), the genetic material of the original (parent) cell is divided up twice. As in most other cells in the body, the nucleus of the original cell contains the person’s full set of genetic information.

Detailed explanation-2: -The purpose of meiosis is to produce gametes, or sex cells. During meiosis, four daughter cells are produced, each of which are haploid (containing half as many chromosomes as the parent cell).

Detailed explanation-3: -Mitosis is essential for asexual reproduction, regeneration, and growth. It does not make sex cells or gametes.

Detailed explanation-4: -In females, the process of meiosis is called oogenesis, since it produces oocytes and ultimately yields mature ova(eggs). The male counterpart is spermatogenesis, the production of sperm.

Detailed explanation-5: -Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.
