WebSilent mutations are mutations in DNA that do not have an observable effect on the organism's phenotype. They are a specific type of neutral mutation.The phrase silent mutation is often used interchangeably with the phrase synonymous mutation; however, synonymous mutations are not always silent, nor vice versa. Synonymous mutations … WebIn other cases, individuals that carry the same mutation show a range of phenotypes that vary in their severity. The relative consistency of the phenotype produced by a particular mutation is referred to the mutation’s expressivity.
