• Mutation is a change in an organism’s genetic material. Mutations happen at a certain rate, and they happen at random anywhere in the organism’s genetic material. Some of these mutations are neutral, some are deleterious (have harmful effects for the organism’s body) and some are advantageous (impart the organism with some positive trait, that ensures better survival).
