Why is genetic diversity important for species like cheetahs?

Genetic diversity is crucial for the survival and adaptability of species like cheetahs because it enhances their ability to cope with changing environments. When a species has a wide range of genetic variations, it can better withstand environmental stresses such as climate change, disease outbreaks, and habitat alterations. For instance, if a new disease affects a population, individuals with different genetic traits may have varying levels of resistance, allowing some to survive and reproduce, thereby ensuring the continuity of the species.

In contrast, a lack of genetic diversity can lead to inbreeding, which may increase the likelihood of hereditary diseases and decrease the overall fitness of the population. This genetic homogeneity can render the species more vulnerable to extinction in the face of environmental challenges. Therefore, maintaining genetic diversity is vital for the resilience of cheetahs and other species, enabling them to adapt over time and survive in a dynamic ecosystem.
