Which developmental consequence results when ecdysone production ceases prematurely during metamorphosis of Drosophila melanogaster?

💡 Explanation

When ecdysone production ceases prematurely, then the necessary hormonal signaling regulating the activation of genes required for terminal differentiation is lost because the cascade triggers transitions critical for developing adult tissues cannot proceed. Therefore adult structure differentiation is impaired, rather than molting, puparium formation, or disc halting, all dependent on active ecdysone signaling periods.
