← Nature & AnimalsWhich consequence results when premature ecdysone shutdown in moth larvae?
A)Giant but infertile adult moths
B)Larval diapause termination failure
C)Smaller but viable adult moths
D)Incomplete pupal transition arrest✓
💡 Explanation
Incomplete pupal transition results because insufficient ecdysone prevents proper metamorphic changes; because the steroid triggers receptor expression, tissue specification and developmental reprogramming mechanisms, therefore arrested development results rather than diapause, giantism, or normal metamorphosis.
