The main advantage of sexual reproduction over asexual reproduction is the enhancement of genetic diversity. Sexual reproduction involves the combination of genetic material from two parents, resulting in offspring with diverse traits. This genetic variation increases a population's adaptability to changing environments, promotes resilience against diseases, and improves the chances of survival. In contrast, asexual reproduction produces genetically identical offspring, which may be less capable of coping with environmental changes. The higher adaptability associated with sexual reproduction is crucial for the long-term survival and evolution of species.
