Flower symmetry in Antirrhinum species.
Issue Image

All species show bilateral symmetry, yet genes controlling flower symmetry vary in expression between species. Cryptic variation of this kind for multiple genetic loci may underlie the phenomenon of hybrid vigor (see Rosas et al., e1000429). Species from left to right, and top to bottom: A. australe; A. linkianum; A. mollissimum; A. sempervirens; A. striatum; A. charidemi; A. molle; A. pseudomajus; A. graniticum; A. siculum; A. hispanicum; A. lopesianum; A. pulverulentum; A. litigiosum; A. latifolium; A. tortuosum.
