Question
Why is mitosis called equational division?
Advertisements
Solution
- Chromosomes multiply and equally distribute between the two daughter nuclei during mitosis, a type of cell division that results in daughter cells that have the same number and kind of chromosomes as the parent cell.
- Thus, the term equational division is used to describe mitosis.
