b.For the introduction of variation, which eventually acts as the raw material for evolutionary forces.
c.For the inheritance of the genetic constitution so that species continuity can be maintained.
2. Which is a better mode of reproduction sexual or asexual? Why?
Sexual reproduction is considered to be a better mode of reproduction because it creates a hybrid that has more vigour than the parents. It also leads to variations that enable organisms to adapt to the changing or prevailing environment.
