Answer 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).
