Which outcome occurs when imaginal disc cells fail to differentiate correctly in insect metamorphosis?

💡 Explanation

When imaginal disc cells fail to differentiate properly, developmental gene expression is disrupted because of signaling pathway failures, resulting in the production of non-functional or malformed adult features. Therefore deformed structures result, rather than earlier molting, changed growth, or programmed cell death, which require different signaling or hormonal misregulation.
