Single gene effects on the wing pattern of Bicyclus anynana. Top row shows the forewing, and bottom row, the hindwing. The left hand column with dark background shows the wild type wing pattern of the ventral hindwing (d) and dorsal forewing (a): a, anterior eyespot; p, posterior eyespot with g, outer gold ring; b, inner black disc and w, central white pupil. The four panels with light background are all mutant phenotypes: (b) Spotty (dorsal); (c) Bigeye and Spotty double mutant (ventral); (e) Cyclops (ventral; the central two eyespots of the wildtype have coalesced); (f) comet (ventral).
