Which process is disrupted in metamorphic insects when exposed to juvenile hormone analog during the pupal stage?

💡 Explanation

When juvenile hormone analog persists during the pupal stage, the normal timing for expression of genes in imaginal discs is disrupted because it maintains larval characteristics instead of triggering adult development. Therefore imaginal disc gene expression is affected, rather than cuticle deposition, fibroin secretion, or prothoracic gland reactivation, which involve other developmental stages and hormone signals.
