Definitions related to genetic polymorphism:
-
(polymorphism) A common change in the genetic code in DNA. Polymorphisms can have a harmful effect, a good effect, or no effect. Some polymorphisms have been shown to increase the risk of certain types of cancer.NCI Dictionary of Cancer TermsU.S. National Cancer Institute, 2021
-
Simultaneous occurrence in the population of genomes showing allelic variations such as different phenotypes or restriction maps.CRISP ThesaurusNational Institutes of Health, 2006
-
The regular and simultaneous occurrence of alternative nucleotide sequences at equivalent locations of the genetic material among individuals of a single interbreeding population that are not maintained by recurrent mutation. Polymorphisms may range in size from single nucleotide to large nucleotide sequence variation visible at the chromosomal level.NCI ThesaurusU.S. National Cancer Institute, 2021
-
(polymorphism, genetic) The regular and simultaneous occurrence in a single interbreeding population of two or more discontinuous genotypes. The concept includes differences in genotypes ranging in size from a single nucleotide site (POLYMORPHISM, SINGLE NUCLEOTIDE) to large nucleotide sequences visible at a chromosomal level.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
