Genetic variation refers to diversity in gene frequencies. Genetic variation can refer to differences between individuals or to differences between populations.Mutation is the ultimate source of genetic variation, but mechanisms such as sexual reproduction and genetic drift contribute to it as well.enetic variation refers to diversity in gene frequencies. Genetic variation can refer to differences between individuals or to differences between populations.
The combination of different alleles is an individualâs genotype. Natural selection acts on phenotype, not genotype. Genetic variation and evolution are studied in populations. Members of a population share a common group of genes, called a gene pool.Allele frequency is the number of times an allele occurs in a gene pool compared with the number of times other alleles for the same gene occur.n genetic terms, evolution is any change in the allele frequency in a population. Sources of Genetic Variation The three main sources of genetic variation are mutations, genetic recombination during sexual reproduction, and lateral gene transfer. A mutation is any change in a sequence of DNA.
