Fig. 2. Rescue of Wg signaling in the wing. Minute clones of fz2C1,fzH5 were induced in wings in the presence of (A) tub-1/1/1, (B) tub-1/2/2, (C) tub-2/1/1 and (D) tub-2/2/1. Clones were marked by the loss of the yellow marker. Arrowheads indicate non-mutant (yellow) bristles. In the presence of the tub constructs large healthy patches of mutant tissue identified by yellow bristles are present. Polarity defects are not rescued. The 3 chimeras shown are those that failed to rescue polarity in the eye. All chimeras tested showed rescue.
