Fig. 2. Eye phenotypes for mutations in the hh pathway. (A)Wild-type eye. (B-F) Eyes carrying mutant clones for smo³ (B), ttv^l(2)00681 (C), hh^SH2(D), disp^SH23 (E) or cmn^M82 (F). Loss-of-function mutations in the positive regulators of the hh pathway induce eye phenotypes similar to a hh mutation.
