Which consequence results when larval insect imaginal discs fail to receive ecdysone signal during metamorphosis?

💡 Explanation

When imaginal discs do not receive the ecdysone signal, apoptosis regulation is altered because ecdysone triggers expression of genes responsible for transition, preventing differentiation of adult tissues. Therefore adult structure development fails, rather than the disruption of hormonal regulation, molting halting, or aberrant differentiation which are triggered either by specific genes or premature hormones.
