WebPhenotypic Variation by Mutations. Mutations can produce viruses with new antigenic determinants. The appearance of an antigenically novel virus through mutation is called antigenic drift. Antigenically altered viruses may be able to cause disease in previously resistant or immune hosts. 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.
