Fig. 5. shar-pei mutant retinas contain more photoreceptor clusters than
wild type. The numbers of photoreceptor clusters in 18 wild-type (wt) and 18
eyFLP induced shrp1 mosaic retinas were counted
in whole mid-pupal retinas. Photoreceptor clusters were visualized by
Elav-GAL4 driven GFP expression. Each square/triangle represents one
retina.
