Detailed explanation-1: -Genetic variations that alter gene activity or protein function can introduce different traits in an organism. If a trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection).
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: -In a genetically diverse population, there will be many traits present. A species is more likely to survive if it is genetically diverse, because it has a variety of different possible adaptations. Darwin studied how populations changed over time.
Detailed explanation-4: -A genetically diverse population of individuals is more likely to survive than a population of individuals with similar genetic makeup. Variation allows some individuals within a population to adapt to the changing environment and natural selection allows the expression of those beneficial traits to persist.
