← Nature & AnimalsWhich outcome results when specific inhibitory signals prevent imaginal disc eversion in Drosophila pupae?
A)Complete transformation requires hormone gradient
B)Apoptosis is induced, halting metamorphosis✓
C)Larval features prematurely displayed externally
D)Pupal case detaches too early disrupting protection
💡 Explanation
When inhibitory signals block the eversion stimulated from from imaginal discs, apoptosis occurs because gene regulatory networks fail to orchestrate tissue remodeling, therefore the development arrests midway rather than completing it involving tissue organization changes triggered by hormone secretion.
