Detailed explanation-1: -Neutral mutations are changes in DNA sequence that are neither beneficial nor detrimental to the ability of an organism to survive and reproduce. In population genetics, mutations in which natural selection does not affect the spread of the mutation in a species are termed neutral mutations.
Detailed explanation-2: -The majority of mutations have neither negative nor positive effects on the organism in which they occur. These mutations are called neutral mutations. Examples include silent point mutations. They are neutral because they do not change the a mino acid s in the proteins they encode.
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: -Neutral mutations are not subject to selection because they do not affect fitness. Neither do they affect morphology, physiology, or behavior.
Detailed explanation-5: -Polyploidy in plants is an example of neutral mutation, where flowers of same plant show difference in color or show two colors.
