<span>Variations in asexual organisms are rather rare since they occur as a result of mistake of mitosis during DNA copying. On the other hand, variations in sexual organisms are a result of fusion of two different gametes that carry different traits. Thus, the offspring carries characteristics of both parents, resulting in greater genetic variation within the next generation. Consequently, sexual organism obtain greater genetic variation than asexuallt reproducing species.</span>
