StellarThe Role of Genetic Diversity in Population Dynamics
Genetic diversity within a species or population is critical for its survival and adaptability. Populations with high genetic variation are more likely to contain individuals with traits that confer resilience to environmental changes. For instance, when faced with a disease outbreak, a diverse population may include individuals resistant to the pathogen, enabling the population to recover and persist. Conversely, populations with low genetic diversity, such as the endangered California condors or black-footed ferrets, are more vulnerable to environmental pressures and face a heightened risk of decline or extinction.
