What is somatic mutations?
Any mutation that happens in a cell other than a gamete, germ cell, or gametocyte is referred to as a somatic mutation because it involves a change in the DNA sequence of a somatic cell of a multicellular organism with dedicated reproductive cells. Somatic mutations are typically not passed on to descendants, in contrast to germline mutations, which can be transmitted to an organism's offspring. Plants, which lack a separate germline, and animals that can reproduce asexually by processes like budding, as in the case of members of the cnidarian genus Hydra, obfuscate this distinction.
The descendants of a cell inside the same organism will all carry somatic mutations, even if somatic mutations are not passed on to an organism's progeny.
