hh^Mrt is enhanced by swm. Wings: (A) wild type, (B) hh^Mrt/+, (C) and (D) swm^Dh-1/+; hh^Mrt/+. Third instar wing imaginal discs were stained for Ptc (E, F, and G) or Ci (H, I, and J) protein. Genotypes are as follows: (E and H) wild type; (F and I) hh^Mrt/+; and swm^Dh-1/+; (G and J) hh^Mrt/+. The arrows indicate ectopic expression of Ptc and Ci in the anterior compartment along the dorsal ventral compartment boundary.
