WebJan 20, 2024 · During mitosis, a cell with 2n chromosomes replicates the chromosomes to increase the number to 4n. The cell then eventually divides to form two daughter cells with 2n chromosomes each forming diploid daughter cells. Thus, mitosis converses with the chromosome number in all cells. Mitosis division is the main form of growth in all … WebPrior to each mitotic division, a copy of every chromosome is created; thus, following division, a complete set of chromosomes is found in the nucleus of each new cell. citing chicago style footnotes
