Detailed explanation-1: -Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies-or ‘replicates’-its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set. Your body contains trillions of cells (thousands of millions).
Detailed explanation-2: -Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.
Detailed explanation-3: -Then in mitosis, the sister chromatids of each chromosome separate, so each daughter cell receives one chromatid from each chromosome. The result of mitosis is two identical daughter cells, genetically identical to the original cell, all having 2N chromosomes.
Detailed explanation-4: -The cells of all living things are composed of a substance called protoplasm. Most cells reproduce by dividing into two identical cells called neutral cells.
