Source sentences:
text: Most mutations within genes are neutral, having no effect on the organism's phenotype (silent mutations).
text: Other mutations can be neutral if they lead to amino acid sequence changes, but the protein still functions similarly with the new amino acid (e.g. conservative mutations).
text: Mutations within introns and in regions with no known biological function (e.g. pseudogenes, retrotransposons) are generally neutral, having no effect on phenotype - though intron mutations could alter the protein product if they affect mRNA splicing.
text: In this latter case the mutation will have little or no effect on phenotype and therefore be neutral.
text: A fitness of zero, less than one, one, more than one, respectively, indicates that mutations are lethal, deleterious, neutral, and advantageous.
text: Although most mutations that change protein sequences are harmful or neutral, some mutations have benefits.
