Somatic vs Germline Mutations
In multicellular organisms, mutations can be classed as either somatic or germ-line:
- Somatic mutations – occur in a single body cell and cannot be inherited (only tissues derived from mutated cell are affected)
- Germline mutations – occur in gametes and can be passed onto offspring (every cell in the entire organism will be affected)
