Detailed explanation-1: -After mutagen treatment, the vast majority of base pair changes (especially substitutions) have no effect on the phenotype. Often, this is because the change occurs in the DNA sequence of a non-coding region of the DNA, such as in inter-genic regions (between genes) or within an intron region.
Detailed explanation-2: -Mutations, however, occur not only when copying DNA, but also when building the phenotype, especially when translating and transcribing DNA to RNA and protein.
Detailed explanation-3: -Silent 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.
Detailed explanation-4: -An organism carrying mutated gene or genes is called a mutant. Mutation may change expression of a gene, leading to a different phenotype of the mutant in comparison to the form from which it arose.
