Which disruption occurs when ecdysone signaling is prematurely activated in Drosophila imaginal discs?

💡 Explanation

When ecdysone signaling is prematurely activated, precocious specification occurs because the hormone triggers premature activation of transcription factors, accelerating the cell differentiation into adult structures. Therefore cell differentiation results, rather than other options which require the later stages of metamorphosis or involve the absence of ecdysone.
