Somatic cells are usually diploid, except where there is polyploidy. Either way, somatic cells have double the number of chromosomes that gametes in the same organism have. Somatic cells divide by mitosis and make identical copies of themselves, while gametes are made when germ cells divide by meiosis.
In humans, somatic cells have 46 chromosomes.
