Answer 1

Mutation is a change in the genetic material (chromosomes or genes) of an organism. It can be caused by external factors such as the environment, or by errors during replication or repair of DNA. Mutations can result in new genetic variations, which may have positive, negative, or neutral effects on the organism's traits and overall fitness.
