Which signaling malfunction during metamorphosis leads to malformed adult wings in insect imaginal discs?

💡 Explanation

During metamorphosis, accurate wing development relies on Hedgehog signaling regulating cell fate and patterning within imaginal discs; when Hedgehog signaling is downregulated, proper wing venation and shape formation is disrupted. Therefore, diminished Hedgehog signaling leads to malformed wings rather than changes apoptosis, juvenile hormone, or cuticle synthesis which affect other developmental processes.
