A human cell has 46 chromosomes in total. Out of these 46 chromosomes, 44 are autosomes and 2 are sex chromosomes. Chromosomes occur in pairs and thus there are 23 pairs. A cell having 23 pairs of the chromosome is called diploid. Diploid cells undergo division and their number reduces to half, i.e.produce haploid cells having only 23 chromosomes, without any pairs. These cells are also called gametes. Thus, gametes have only one sex chromosome.
