Answer: 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.
Genetic variation means that a specific gene has various alleles. ... Genetic variation makes it possible for a species to exhibit various traits related to that specific gene. Having a variety of traits can help species adapt to different environmental conditions over time.
