Here's why:
* 2n represents the diploid state, meaning the cell has two sets of chromosomes.
* Mitosis is a type of cell division where a single cell divides into two identical daughter cells, each with the same number of chromosomes as the parent cell.
* Meiosis, on the other hand, is a type of cell division where a single cell divides into four daughter cells, each with half the number of chromosomes as the parent cell (n).
Therefore, 2n to 2n signifies that the chromosome number remains the same, which is characteristic of mitosis.
