Detailed explanation-1: -Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others. Individuals with adaptive traits-traits that give them some advantage-are more likely to survive and reproduce.
Detailed explanation-2: -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-3: -Variation promotes the survival of species in the following ways: Variation improves the survival rate of species as it helps the individual organisms adapt based on altering environmental conditions. Variants formed due to environmental concerns form the basis for evolution.
Detailed explanation-4: -Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.
Detailed explanation-5: -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.
