Which developmental consequence occurs when imaginal discs in Drosophila lack ecdysone receptors?

💡 Explanation

When imaginal discs lack ecdysone receptors, proper hormonal signaling for metamorphosis is disrupted because ecdysone cannot trigger the transcription of genes responsible for adult structure development. Therefore, the wings fail to properly develop, rather than premature molting, extended lifespan or duplicated boundaries, which occur through other signaling pathways.
