Higher organisms have resorted to sexual replication even after having such complexity because offspring of sexual reproduction have variations in their genes which helps their survival. It helps organisms to adapt to the environment easily. This is due to the fact that during sexual reproduction, the gametes of both of the parents, male and female, come together and fuse. Thus, the offspring tends to have the genetic material or information carried from both the parents. This means that it involves the fusion of gametes of both the individuals i.e male and female to produce zygotes. This variation which was developed in offspring enables them to adapt to changing and challenging environments.
