An advantage of sexual reproduction over asexual reproduction is that sexual reproduction does what?

The prevailing theory is that sexual reproduction, which requires two genders, allows genetic intermingling that overall is very good for both the individuals and the species as a whole. Asexual reproduction, on the other hand, is largely static, where each offspring is genetically identical to every other.

Include components from both partners, effectively creating a better version of either entity. It also keeps diversity up, thus allowing for a better gene pool.
