During sexual reproduction male and female gametes from male and female individuals respectively fuse with each other and form zygote. This zygote contains new combinations of DNA/genes that are a result of recombination and crossing over. Due to the presence of these new combinations of DNA, variations are caused. These variations allow organisms to survive in unfavourable conditions. This is the reason why offsprings formed due to sexual reproduction have better chances of survival over those formed due to asexual reproduction. 

The above statement is not always true, because there have been instances when continuous sexual reproduction among species of a given population, causes a reduction in yield and reduces the chances of survival. It mainly occurs because, sometimes due to recombination, less desired combinations of DNA/genes are formed and they make species vulnerable to extreme conditions. Thus, the statement, offspring formed due to sexual reproduction have better chances of survival is not always true.
