Difference: in asexual reproduction only one parent is involved and no gametes are formed, whereas in sexual reproduction two parents (a male and a female) are involved, and male and female gametes are formed and fuse. The species reproducing sexually has comparatively better chances of survival. Reason: sexual reproduction combines DNA from two individuals and so generates more variation among the offspring. When the environment changes, some of these variants are likely to suit the new conditions; they survive and reproduce, so the species is not wiped out.
