    It's actually about avoiding it:

    Sex is not about promoting genetic variation, researchers argue

    "If sex was merely for increasing genetic diversity, it would not have evolved in the first place," said Heng. This is because asexual reproduction -- in which only one parent is needed to procreate -- leads to higher rates of genetic diversity than sex.
    For nearly 130 years, traditional perceptions hold that asexual reproduction generates clone-like offspring and sexual reproduction leads to more diverse offspring. "In reality, however, the relationship is quite the opposite," said Heng.
    And not only does asexual reproduction lead to higher rates of genetic diversity, it also is two times more efficient than sexual reproduction.

    Cant' tell you how many horrible endings I've seen during competitive sexual reproduction.. Certainly NOT efficient or even safe... Don't try it at home!
