Evolution and Genetic Diversity Quiz

Genetic diversity is necessary for evolution by natural selection to occur because it allows for a greater chance of individuals having characteristics suited to environmental changes.

Selective advantage refers to the characteristics that make an organism more likely to survive, reproduce, and pass on favorable alleles to the next generation.

Natural selection drives evolution by selecting for organisms with variations that provide a better chance of survival and reproduction in a given environment.
