The gametes are the germ cells formed in the organisms which are formed through the process of meiosis.
Since the gametes are formed through meiosis, therefore, each gamete cell will be a haploid cell that is half the ploidy level of a somatic cell.
Therefore, if the number of the chromosome in the epithelial cell will be 24 chromosomes then the chromosome number present in the germ cells will be half the ploidy level to maintain the haploidy thus, the germ cells will contain 12 chromosomes.
