Gamete is a reproductive cell that always contains a single number of chromosomes. A somatic cell is a structural unit in a living organism that carries a double number of chromosomes. This double number of chromosomes is restored when two different germ cells merge. As a result, a zygote is formed. And as a result of its subsequent division, many somatic cells of the body are formed. Therefore, if a green toad has 13 chromosomes in its germ cells – this is a haploid set, then its somatic cells will have 26 (13 x 2 = 26) chromosomes.
