What does genetic diversity within a population enhance?

Genetic diversity within a population enhances resilience to environmental changes by increasing the range of traits present in the population. This variety means that some individuals may possess adaptations that allow them to survive and reproduce under different environmental conditions, such as changes in climate, availability of resources, or the presence of new diseases. When a population is genetically diverse, it is more likely to include individuals with advantageous traits that can cope with these changes, ensuring the survival of the species over time. In contrast, a population with low genetic diversity may struggle to adapt and could face higher risks of extinction when confronted with environmental pressures.
