How can a mutation cause variation
WebGenetic Variation Mutation; 1. Genetic Variation leads to changes in the allele or gene frequencies in a population. Mutation causes a permanent change in the genetic … WebAbstract. Natural selection can adjust the rate of mutation in a population by acting on allelic variation affecting processes of DNA replication and repair. Because mutation is the ultimate source of the genetic variation required for adaptation, it can be appealing to suppose that the genomic mutation rate is adjusted to a level that best ...
