WebThe somatic cells of the human body—that is, the cells that aren’t gametes, or sex cells—each have 46 chromosomes. They are diploid cells, which means that those 46 chromosomes are organized into 23 pairs. Diploid is sometimes abbreviated as 2n (where n is the number of different chromosomes). 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.
