Question

How does sexual reproduction give rise to more viable variation than asexual reproduction?

Answer 1

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. The genes of the traits or characteristics are transmitted from one generation to the next generation and dominant characters are expressed. While in asexual reproduction, gene cannot be separated from the parent organism. The resulting variation in traits out of sexual reproduction not only help in survival of species but also support diversity in long run. Drift in genetic traits get accumulated spanning across generations, this gives rise to formation of new species.
