Detailed explanation-1: -Sexual reproduction generates more variations than asexual reproduction. This happens because of contribution of DNA from two parents with their own variations which produces a novel combination in the offspring. Though asexual reproduction produces variations which are less in number.

Detailed explanation-2: -Asexual reproduction generates offspring that are genetically identical to a single parent. In sexual reproduction, two parents contribute genetic information to produce unique offspring.

Detailed explanation-3: -Summary. Sexual reproduction has the potential to produce tremendous genetic variation in offspring. This variation is due to independent assortment and crossing-over during meiosis, and random union of gametes during fertilization.

Detailed explanation-4: -Asexually reproducing organisms spend fewer resources for the same reproductive output, meaning their populations grow and expand faster than sexually reproducing ones. On the other hand, asexual populations have reduced genetic diversity and, hence, lower adaptability to changing environments.
