Which signaling cascade disruption prevents full wing formation when juvenile insect molts to pupal stage?

💡 Explanation

During insect metamorphosis, ecdysone triggers molting; receptor downregulation reduces the hormonal signal initiating cell differentiation within imaginal discs, preventing wing development. Therefore receptor downregulation results in wing formation failure, rather than alternative disruptions affecting apoptosis, hedgehog signaling, or immune response feedback.
