Sample Entry:

mutation (my-t'shn) A change in the genes or chromosomes of an organism. Mutations occurring in the reproductive cells, such as an egg or sperm, can be passed from one generation to the next. Most mutations have harmful effects, but some can increase an organism's ability to survive. A mutation that benefits a species may evolve by means of natural selection into a trait shared by all members.
