Clones expressing DllScer\UAS.cWa under the control of Scer\GAL4Act5C.PP are recovered in the central region of the leg disc at high frequency, but are under represented or not recovered in the proximal region of the disc (depending on the stage of induction of the clone). Clones that are recovered in the proximal region of the leg disc appear to be segregating from the disc epithelium.
