Brit.

/əˈliːl/,

/ˈaliːl/, U.S.

/əˈlil/

Forms: 1900s– allel (rare), 1900s– allele.

Origin: Formed within English, by clipping or shortening. Etymon: allelomorph n.

Etymology: Shortened < allelomorph n. Compare German allel allelomorphic (1923). Compare earlier allelism n.

Genetics.

Each of two or more alternative forms of a gene that arise by mutation and which may be found in the same position on a homologous chromosome. Cf. allelomorph n.
