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?

A germline mutation occurs in reproductive cells, such as sperm or egg cells, and can potentially be passed to offspring. A skin cell is a body (somatic) cell, so a mutation in it is not a germline mutation. Missense and nonsense describe effects on a protein’s code, not whether the mutation is in a reproductive cell or a body cell.
