Amino acid replacement: S554E.
Amino acid replacement: S560E.
Expression of mutated fz is under the control of UAS sequences.
abnormal planar polarity, with Scer\GAL4sev.PM181
ommatidium, with Scer\GAL4sev.PM181
The polarity of ommatidia is only weakly disturbed by fzEE.Scer\UAS; Scer\GAL4sev.PM181. No symmetrical ommatidia are seen in the eyes of these flies.
