What is another word for neutral mutation?
Pronunciation: [njˈuːtɹə͡l mjuːtˈe͡ɪʃən] (IPA) 
Neutral mutation refers to a genetic alteration that doesn't affect the fitness of an organism. There are several synonyms of this term, such as silent mutation, synonymous mutation, and non-synonymous mutation. A silent mutation is a type of genetic change that doesn't change the amino acid sequence of a protein and consequently doesn't affect the function of the protein. On the other hand, a synonymous mutation alters the nucleotide sequence of a DNA molecule, but the amino acid sequence of a protein remains the same. Lastly, non-synonymous mutation is a genetic change that modifies the amino acid sequence of a protein, although this change doesn't always affect the function, structure, and stability of the protein.
