Answer:
★Explanation:
Mitosis and meiosis are both types of cell divisions, but they are different.
Mitosis
- cell division that results in
- daughter cells used for growth, repair, and development
The cells are genetically identical with the same number of chromosomes as the parent cell.
Meiosis
- cell divisions resulting in 4 daughter cells for sexual reproduction
The cells are genetically different and have half the number of chromosomes as the parent.
The organism has 20 chromosomes.
Mitosis: same number of chromosomes=20
Meiosis: half the chromosomes= 20/2= 10
- After mitosis, the daughter cell has 20 chromosomes.
- After meiosis, the cell has 10.
