As we saw in Section 17, normal cells pass through the cell cycle only a finite number times. Once a cell can no longer undergo mitosis, cell death occurs. 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.
