The correct response is: Somatic cell mutations are not passed to the next generation.
Somatic cells are the body cells that make up most of an organism, while gametes are the reproductive cells (sperm and eggs). Somatic cells contain the full set of chromosomes (diploid), while gametes contain half (haploid). Additionally, mutations in somatic cells do not get transmitted to the next generation, whereas mutations in gametes can be passed on.
