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 is a fundamental process for life. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.
Detailed explanation-3: -The daughter cells formed are identical to the parent cell as there is no crossing over (as opposed to meiosis). Mitosis contributes to the growth and repair of tissues in multicellular organisms.
Detailed explanation-4: -There are now two cells, and each cell contains half the number of chromosomes as the parent cell. In addition, the two daughter cells are not genetically identical to each other because of the recombination that occurred during prophase I (Figure 4).
