What is an advantage of sexual reproduction compared to asexual reproduction?

Sexual reproduction provides a significant advantage in producing populations that are less susceptible to catastrophic changes because it promotes genetic diversity. In sexual reproduction, offspring are produced through the combination of genetic material from two parents, which results in offspring with varied genetic traits. This genetic variability is crucial for populations to adapt to changing environments, diseases, and other challenges.

When a population has a diverse gene pool, it is more likely to include individuals with traits that enable some to survive and thrive under new or adverse conditions. For example, if a disease affects a specific genotype, individuals with different genetic configurations may be unaffected, ensuring the survival of the population.

In contrast, asexual reproduction typically results in genetically identical offspring, making the entire population more vulnerable to the same environmental pressures or diseases, as they all share the same traits and weaknesses. This lack of diversity can lead to lower survival rates when faced with changes or threats. Therefore, the ability of sexual reproduction to increase genetic diversity is a critical advantage in the evolutionary context.
