← Nature & AnimalsWhich developmental consequence occurs when hormone signaling malfunctions during imaginal disc metamorphosis in Drosophila?
A)Antennae develop instead of legs.✓
B)Wings develop without vein structures.
C)Eyes develop as separate structures.
D)The fly completes larval stages fully.
💡 Explanation
When hormone signaling malfunctions, cellular differentiation is disrupted, because precise hormone levels trigger specific gene expression in imaginal discs, determining segment and appendage identity resulting in homeotic transformations. Therefore, antennae instead of legs may result, instead of normal wing formations, separable eyes, or persistent larval forms which require coordinated regulation.
