How does variation affect an organism?

Explanation:

Genetic variation in a group of organisms enables some organisms to survive better than others in the environment in which they live. Organisms of even a small population can differ strikingly in terms of how well suited they are for life in a certain environment. An example would be moths of the same species with different color wings.

Some organisms survive in their environment better than others due to genetic variation in a group of organisms. Even within a small population, organisms can differ dramatically in how well adapted they are to life in a given environment.
