The FRT cassette has been excised, juxtaposing the sev enhancers and heat shock promoter with the fz2 coding sequences.
fz22-2-2.hs.2sev is a non-suppressor of abnormal planar polarity phenotype of fz37/fz15
fz22-2-2.hs.2sev is a non-suppressor of ommatidium phenotype of fz37/fz15
fz22-2-2.hs.2sev does not rescue the tissue polarity defect seen in fz37/fz15 eyes.
