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
