"When you think about sexual reproduction, it makes no sense. After all, evolution selects for organisms that are best fit. In a population of sexually reproducing organisms, a mutant that reproduced asexually would increase its representation more quickly than the wild type; that is, it would have a higher fitness. So we should expect asexual reproduction to be much more widespread among eukaryotic species than it is."

That is a rough one.  There are a lot of different publications that deal with this.  There are a lot of works that also show that mathematically, sexual reproduction should go extinct.  I think if you do a bit of research you can come up with enough to justify your answer, no matter which way you go.
