UAS sequences regulate expression of mutated fz (amino acid replacements S554A, S560A).
abnormal planar polarity, with Scer\GAL4sev.PM181
ommatidium, with Scer\GAL4sev.PM181
photoreceptor cell R3 | ectopic, with Scer\GAL4sev.PM181
photoreceptor cell R4, with Scer\GAL4sev.PM181
The ommatidia of fzAA.Scer\UAS; Scer\GAL4sev.PM181 adult eyes have random chirality and some are symmetrical, with two R3 photoreceptors in place of an R3/R4 pair. This result is identical to that seen with fzScer\UAS.cAa.
