Brit.

/ˌalə(ʊ)ˈpɒlᵻplɔɪdi/, U.S.

/ˌæloʊˈpɑləˌplɔɪdi/,

/ˌæləˈpɑləˌplɔɪdi/

Origin: Formed within English, by compounding; modelled on a German lexical item. Etymons: allo- comb. form, polyploidy n.

Etymology: < allo- comb. form + polyploidy n., after German Allopolyploidie (H. Kihara & T. Ono 1926, in Zeitschr. f. Zellforsch. u. mikroskop. Anat. 4 480). Compare autopolyploidy n., allopolyploid adj.

Biology.

The state or condition of being allopolyploid; the act or process of a hybrid becoming a new species by polyploidizing.
