Interaction of Mutation with Selection
In any real population, mutation will be taking place. There will also be natural selection, and, in the case of domestic plants or animals, there may be artificial selection as well. Selection, either artificial or natural, tends to increase the frequency of one allele at a given locus until that allele is in the preponderance. Mutation tends to decrease the frequency of the preponderant allele. Thus, it is almost inevitable that selection and mutation will have opposite effects on allele frequencies.
