Write one difference between asexual and sexual mode of reproduction

Write one difference between asexual and sexual mode of reproduction. Which species is likely to have better chances of survival - the one reproducing asexually or the one reproducing sexually ? Justify your answer.

(i) Asexual mode of Reproduction : Only one parent involved.
Sexual mode of Reproduction : Two parents (male and female) involved.
(ii) Species that reproduces sexually have better chances of survival because more variations are produced during DNA copying which means that there is combining of germs cells of two different individuals (having quite different patterns of accumulated variations.)
