Final answer:
Sexually reproducing organisms have the advantage of producing genetically diverse offspring, which increases their chances of survival and reproduction in changing environments.
Step-by-step explanation:
The advantage that populations of sexually reproducing organisms have over asexually reproducing organisms is that sexual reproduction produces genetically diverse offspring. This genetic diversity allows sexually reproducing individuals to have a better chance of surviving and reproducing in unpredictable or changing environments. While asexual reproduction can result in faster population growth, the lack of genetic variation limits the ability of asexual populations to adapt to changes in their environment.
