There are several key features and advantages associated with the genetic variation as it is an important factor causing evolution allowing natural selection thus leading to increase or decrease the frequency of alleles in a population.
The other factors causing genetic variation include random mating, mutation, random fertilization and recombination during meiosis between the homologous chromosomes.
