The significance of genetic variation in populations lies in its essential role in fostering adaptability and resilience to environmental changes. Diverse genetic traits within a population enhance the likelihood of survival, as some individuals may possess characteristics that enable them to thrive under new conditions, such as disease resistance or altered climates. This genetic diversity is crucial for the health and stability of ecosystems, as it facilitates natural selection and reduces the risk of extinction. Conserving genetic variation is therefore vital for maintaining both species populations and overall biodiversity.
