| 释义 | > as lemmasˈaneuˌploidy ˈaneuˌploidy n. the condition of being aneuploid; an instance or type of this condition. [After German Aneuploidie (G. Täckholm 1922, in Acta Horti Bergiani 7 234).] Aneuploidy, like polyploidy, is much more common in plants than in animals. Its effects on development and reproduction, which are almost always deleterious in animals, are less predictable in plants, in which it may play a role in speciation.
