Detailed explanation-1: -Variations: Due to recombination and crossing over, sexual reproduction brings about variations in species. Variations are essential for individuality and evolution of species. Better adaptability: Increased variability due to sexual reproduction helps in better adaptability of species.
Detailed explanation-2: -Sexual reproduction gives rise to more viable variation than asexual reproduction. It is because there is an inbuilt tendency to variation during reproduction, both because of errors in DNA copying, and modes of sexual reproduction.
Detailed explanation-3: -A child inherits half of the genetic material from each parent. So, it may be they look alike but they are not identical to their parents. Instead, the child has the combination of characteristics inherited from both parents. Therefore, we can say that in sexual mode of reproduction, greater diversities are generated.
Detailed explanation-4: -The advantages of sexual reproduction over asexual reproduction are that sexual reproduction increases genetic diversity. This can lead to increased resistance to disease, more evolution, and decreased recessive disorders.
