Vedclass · Answer

(D) Sexual reproduction involves the fusion of male and female gametes,which are produced by two parents of the same species.During the formation of gametes,a process called meiosis occurs,which involves genetic recombination (crossing over).This recombination leads to the mixing of $DNA$ from both parents,resulting in offspring that are genetically distinct from their parents and siblings.Therefore,the combination of genetic material from two parents of the same species is the primary reason for increased variation in sexually reproducing organisms.
