NEET BIOLOGY

Detailed explanation-1: -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. These individuals then pass the adaptive traits on to their offspring.

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: -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-4: -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-5: -Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.
