Question

Mutations within an organism can occur in body cells or reproductive cells. Which type of mutation is seen in a sperm cell but not in a skin cell?
somatic mutation
missense mutation
nonsense mutation
germline mutation

Answer 1

germline mutation

Explanation: sperm are reproductive (germ) cells, so mutations in them are germline mutations (heritable). Somatic mutations occur in body cells (like skin); missense and nonsense mutations are types of point mutations that can occur in either cell type.
