How does sexual reproduction contribute to the evolution of species compared to asexual reproduction?
How does sexual reproduction contribute to the evolution of species compared to asexual reproduction?
- It leads to genetic uniformity, which allows for better adaptation to stable environments.
- It generates genetic variation, which can result in adaptation to changing environments. (correct)
- It allows for faster population growth due to no need for mate selection.
- It reduces the occurrence of harmful mutations due to the involvement of a single parent.
