What is natural selection?

• The process by which individuals with beneficial traits are more likely to survive and reproduce.

• The ability of an individual to choose its traits.

• A random process that changes the traits of organisms.

Why is genetic diversity important in a population?

• It ensures that all individuals are clones of each other.

• It decreases the population's ability to adapt to environmental changes.

• It increases the chances that some individuals will possess traits beneficial for survival in changing environments.

• It makes the population more vulnerable to diseases.
