Mutations
... How are mutations inherited? Only mutations that occur in gametes, or were present when the organism was fertilized, are passed onto offspring. Mutations that occur in body cells (somatic cells) (after an organism has developed) only affect the organism in which they occur and are not passed on. ...

Chapter 8: From DNA to Proteins
... A mutation can break up a gene, or it can make a new hybrid gene, with a new function. Gene mutations can cause the wrong amino acid to be made which can change an entire protein. Impact on Offspring Mutations in sex cells can be passed on to offspring. They are the underlying source of gene ...
