← Nature & AnimalsWhich developmental error arises when juvenile hormone persistently inhibits imaginal disc differentiation during pupation?
A)Retention of larval characteristics✓
B)Premature adult structure development
C)Disrupted ecdysone production cycles
D)Accelerated chitin synthesis in exoskeleton
💡 Explanation
When high juvenile hormone levels inhibit imaginal disc differentiation, it results in the persistence of larval features because juvenile hormone suppresses transcription factors that promote adult development. Therefore, retention of larval characteristics occurs, rather than premature adult structures, disrupted ecdysone cycles, or accelerated chitin synthesis, which require different hormonal balances.
