WebSo, the number of chromosomes remain 14, 14 and 14 in G1, after S and M-phase of interphase. After the genetic material is duplicated and condenses during prophase of mitosis, there are still only 14 chromosomes. First, during the S phase of interphase, the genetic material of a cell is duplicated. WebThe cell goes through 4 steps (prophase, metaphase, anaphase, and telophase.) The cells at the end of the process also have the same amount of chromosomes as the parent cell. At the end, 2 cells are produced. Mitosis is used to make body cells, and occurs in the body.

WebThe number of chromosomes becomes haploid in meiosis I, because the actual sister chromatids are not pulled apart by spindle fibers. For example, if a cell was undergoing meiosis, and had a total of 4 chromosomes in it, then 2 of them would go to one daughter cell, and 2 of them would go to the other daughter cell. That makes 2 haploid cells.
