Detailed explanation-1: -Genetic diversity is important because it gives species a better chance of survival. However, genetic diversity can be lost when populations get smaller and isolated, which decreases a species’ ability to adapt and survive.
Detailed explanation-2: -Maintaining high genetic diversity allows species to adapt to future environmental changes and avoid inbreeding. Inbreeding, which happens when there are small, isolated populations, can reduce a species’ ability to survive and reproduce.
Detailed explanation-3: -Species with a higher diversity have a lower tendency to become extinct. The greater the genetic diversity within a species, the greater is the chance of that species to survive. Conversely, the lower the genetic diversity within a species, the lower is the chance of survival.
Detailed explanation-4: -Genes hold the key to survival. Over time, species have developed traits to help them flourish in their natural environment and survive in changing environments. The more diverse genes a species has, the better its chances of resisting disease, prevailing over other stresses and adapting to changing conditions.
Detailed explanation-5: -Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.
