The Genetic Basis for Evolution: Genetic Variation
... Mutations create new alleles of genes. Many (probably most) of these new alleles do not have any noticeable effect on the organism’s phenotype. Of those that do cause a change in the organism’s phenotype, most are likely to be harmful. But occasionally a mutation might be beneficial or useful! ...
