Higher genetic diversity within a population provides a range of traits that can enhance the stability and resilience of that population in changing environments. This diversity allows populations to adapt to new challenges, such as climate change, habitat destruction, and emerging diseases. When individuals possess a variety of genetic traits, some are more likely to survive and reproduce under different environmental pressures, which promotes the overall health and viability of the population.

In contrast to this correct answer, higher genetic diversity does not lead to increased disease susceptibility; rather, it equips populations with a broader genetic toolkit to combat various threats. Additionally, uniformity of traits across individuals typically results in vulnerability to diseases or environmental shifts, as there would be less variation to allow some individuals to survive. Reduced reproductive success is also contrary to the benefits of high genetic diversity because diverse genetic backgrounds often lead to healthier and more viable offspring, enhancing the potential for successful reproduction across generations.
