Photoreceptor axons do not project correctly in the optic lobe of hdcC111 eye-brain complexes in third instar larvae, while the photoreceptor cells themselves are appropriately specified.
A portion of the axons growing from the dorsal and ventral regions of the eye disc stall within the optic stalk or enter the optic lobe but fail to reach their normal target region in hdcC111 whole-eye Scer\FLP1ey.PN clones in third instar larvae.
