NEET BIOLOGY

Detailed explanation-1: -At this point, nuclear division begins, and the parent cell is divided in half, forming 2 daughter cells. Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes. Each chromosome consists of 2 sister chromatids .

Detailed explanation-2: -The other type of cell division, meiosis, ensures that humans have the same number of chromosomes in each generation. It is a two-step process that reduces the chromosome number by half-from 46 to 23-to form sperm and egg cells.

Detailed explanation-3: -Normally, each cell in the human body has 23 pairs of chromosomes (46 total chromosomes). Half come from the mother; the other half come from the father. Two of the chromosomes (the X and the Y chromosome) determine your sex as male or female when you are born.

Detailed explanation-4: -The daughter cells are also genetically identical to the parent cell. All of the 46 chromosomes in somatic cells divide and then separate through the process of mitosis. The result is two daughter cells that also contain 46 chromosomes.

Detailed explanation-5: -However, where mitosis leads to an exact copy of the chromosomes, meiosis results in producing new cells with exactly half the DNA as the parent cell. Meiosis is how gametes (sperm and eggs) of organisms are created. From a single cell, meiosis produces 4 daughter cells, each with half of the DNA of its parental cell.
