Which morphological defect arises if imaginal disc apoptosis is inhibited during Drosophila metamorphosis?

💡 Explanation

When imaginal disc apoptosis is inhibited, developmental signaling pathways are disrupted because programmed cell death is essential for sculpting and refining structures, leading to incomplete separation of body parts. Therefore, fused or incomplete body parts will result, rather than increased area, extra segments or reduced bristles which involve different control pathways.
