Concept and mechanisms of variation in alleles of genes / From Wikipedia, the free encyclopedia

There are multiple sources of genetic variation, including mutation and genetic recombination.[4] The mutation is the ultimate source of genetic variation, but mechanisms such as sexual reproduction and genetic drift contribute to it as well.[5]
