Fig. 3.

Effects of dsx dsRNA injection on horn development in O. sagittarius males (Upper) and females (Lower). Shown are lateral (Upper row) and frontal (Lower row) views of representative animals, with mock-injected individuals on the left and dsRNA-injected individuals on the right. Horn development did not differ between mock-injected individuals and WT individuals. Open triangles indicate anterior head horns in mock-injected males and the corresponding region in females. Orange triangles indicate posterior head horns in mock-injected females and the corresponding region in males. Filled triangles indicate thoracic horns. (Scale bars: 1 mm.)
