Genetic variation is stored in a population's gene poolâthe combined alleles of all of the individuals in a population. allele frequency An allele frequency is a measure of how common a certain allele is in the population.
There are three sources of genetic variation: mutation, gene flow, and sexual reproduction. A mutation is simply a change in the DNA. Mutations themselves are not very common and are usually harmful to a population. Because of this, mutations are usually selected against through evolutionary processes.Gene flow is the movement of genetic information between different populations. This method increases genetic variation because introducing new alleles into a population increases the amount of diversity.ecause of this, mutations are usually selected against through evolutionary processes.
