Mitosis is also called ‘equational division’ because:
| 1. | the number of chromosomes in both daughter cells are the same |
| 2. | the sum of the number of chromosomes in two daughter cells is equal to the number of chromosomes in the parent cell |
| 3. | each progeny cell receives only one set of chromosomes from the parent cell |
| 4. | the number of chromosomes in the parent and the progeny cells is the same |
