← Nature & AnimalsWhich developmental outcome results when epidermal cells inappropriately express Dpp near imaginal discs?
A)Normal segmentation occurs embryonically
B)Adult appendage development is disrupted✓
C)Larval molting proceeds appropriately.
D)Homeostasis regulates disc cell proliferation
💡 Explanation
Development is disrupted because ectopic Dpp activation causes altered gene expression and cell proliferation during specification, therefore adult appendage formation is abnormal, rather than segmentation, molting, or controlled proliferation resulting.
