n.

1. The act or process of being altered or changed.

2. An alteration or change, as in nature, form, or quality.

3. Genetics

a. A change of the DNA sequence within a gene or chromosome of an organism resulting in the creation of a new character or trait not found in the parental type.

b. The process by which such a change occurs in a chromosome, either through an alteration in the nucleotide sequence of the DNA coding for a gene or through a change in the physical arrangement of a chromosome.

c. A mutant.

4. Linguistics The change that is caused in a sound by its assimilation to another sound, such as umlaut.

mutation  (my-tshn)

A change in the structure of 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 occur in junk DNA and have no discernible effects on the survivability of an organism. Of the remaining mutations, the majority have harmful effects, while a minority 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 some or all members of the species. See Note at sickle cell anemia.
