S*xual reproduction incorporates the process of combining DNA from two different individuals during reproduction.
S*xual reproduction promotes variations among the offsprings of the same parents and provides, opportunities for new combination of characters, Thus playing an important role in the origin of new species.
In as*xual reproduction very little variations occur over generations. As*xual reproduction has a lesser significance for evolution of species as all the offsprings are genetically similar to the parent organism.
