Both being forms of reproduction posses some characteristic advantages.
> Asexual reproduction is an easy way to produce more clones (group of clones refereed as rummest). So at the time of calamity asexual reproduction ensures that more and more individuals of same generations are produced overtime with same genetic content and is helpful in survival of any species. Example : E.coli reproduces every 20 minutes through asexual reproduction.
> Sexual reproduction is a way to ensure variability in an organism. It generates variation in the offspring through crossing over and recombination that makes the progeny more suitable to the environmental features and thus is effective means for survival.
