allele

See also: allèle

English

Etymology

Borrowed from German Allel, shortened from Allelomorph, from English allelomorph. Ultimately from the Ancient Greek prefix ἀλληλ- (allēl-) from ἄλλος (állos, “other”).

Pronunciation

• IPA^(key): /ˈæ.liː.l/
• IPA^(key): /əˈ.liː.l/
• Rhymes: -iːl

Noun

allele (plural alleles)

1. (genetics) One of a number of alternative forms of the same gene occupying a given position, or locus, on a chromosome.
   • 1976, Richard Dawkins, The Selfish Gene, Kindle edition, OUP Oxford, published 2016, page 46:

     Genes are competing directly with their alleles for survival, since their alleles in the gene pool are rivals for their slot on the chromosomes of future generations. Any gene that behaves in such a way as to increase its own survival chances in the gene pool at the expense of its alleles will, by definition, tautologously, tend to survive.

   • 2013 May-June, David Van Tassel, Lee DeHaan, “Wild Plants to the Rescue”, in American Scientist, volume 101, number 3:

     Plant breeding is always a numbers game. […] The wild species we use are rich in genetic variation, and individual plants are highly heterozygous and do not breed true. In addition, we are looking for rare alleles, so the more plants we try, the better.
