Definitions of mutation

  1. ( genetics) any event that changes genetic structure; any alteration in the inherited nucleic acid sequence of the genotype of an organism
  2. ( biology) an organism that has characteristics resulting from chromosomal alteration
  3. ( genetics) any event that changes genetic structure; any alteration in the inherited nucleic acid sequence of the genoof an organism
  4. Change; alteration, either in form or qualities.
  5. Gradual definitely tending variation, such as may be observed in a group of organisms in the fossils of successive geological levels.
  6. As now employed ( first by de Vries), a sudden variation ( the offspring differing from its parents in some well- marked character or characters) as distinguished from a gradual variations in which the new characters become fully developed only in the course of many generations. The occurrence of mutations, and the hereditary transmission, under some conditions, of the characters so appearing, are well- established facts; whether the process has played an important part in the evolution of the existing species and other groups of organisms is a disputed question.
  7. The result of the above process; a suddenly produced variation.
  8. Alteration; change; variation.
  9. Act or process of changing: change: alteration.
  10. Process of changing; change.
  11. The act of changing.
  12. Modification; change.
  13. The act or process of changing; alteration.
  14. Change; alteration.
  15. Gradual variation towards a definite change of structure; discontinuous variation; the theory of De Vries that new forms, differing sufficiently to constitute a new variety, arise spontaneously and remain true.
