Which developmental constraint could prevent full expression of imaginal disc morphology during metamorphosis?

💡 Explanation

When ecdysone signaling insufficient, developmental programs within imaginal discs are disrupted because it is required for triggering appropriate gene expression for adult structure formation, limiting the proper differentiation of adult tissues. Therefore incomplete manifestation occurs, rather than effects to nutrient, fat body or yolk which affect pup maturation and larva-to-larva molting stages, respectively.
