Answer: (D)

Verified step by step guidance

1. Understand the concept of genetic diversity: Genetic diversity refers to the variety of genes within a population. It is crucial for the survival and adaptability of species.
2. Explore how genetic diversity impacts adaptability: Populations with high genetic diversity have a greater range of traits, which can help them adapt to changing environments, such as climate change or new predators.
3. Consider the role of natural selection: In a diverse population, individuals with advantageous traits are more likely to survive and reproduce, passing those traits to the next generation.
4. Evaluate the impact on disease resistance: Genetic diversity can lead to a population having individuals with varying levels of resistance to diseases, increasing the likelihood that some will survive outbreaks.
5. Conclude the benefits of genetic diversity: Overall, genetic diversity enhances a population's ability to adapt and survive in the face of environmental changes, reducing the risk of extinction.
