Which developmental outcome arises when targeted mutation disrupts hedgehog signaling within insect imaginal discs during metamorphosis?

💡 Explanation

When hedgehog signaling is disrupted in imaginal discs, pattern formation is altered because cell-cell communication is corrupted leading to abnormal spatial organization of developing structures, often like structures. Therefore limb duplication results, rather than apoptosis, accleration, or gigantism, which need different genetic or hormonal influences.
