Neutral alleles do not affect the fitness of individuals, so the exchange of b1 for b2 at the b locus would have no impact on an individual's fitness. Selected alleles have a positive or negative impact on fitness, while deleterious alleles have a negative impact on fitness. Missense mutations alter the amino acid sequence of a protein, and neutered is not a term used in genetics to describe alleles.
