Imprecise excision resulting in the deletion of fz3 DNA, including the transcription start site, the first exon and a portion of the intron.
Dorsal cluster neuron axon extension is not affected in the brains of fz3G10 flies.
Homozygotes have few appreciable morphological defects and planar polarity is normal.
The wingless phenotype of wg1/wgl-17 flies is partially rescued by fz3G10; the fraction of flies with two wings increases from 46% to 87%, while the fraction of one wing and wingless flies reduces from 44% and 10% to 13% and 0.5% respectively. The wingless phenotype of wg1 homozygotes is dominantly enhanced by ap78j; no wing blade is formed at approximately 90% of presumptive wing-blade-forming sites. This phenotype is partially suppressed by fz3G10. Most wgl-16/wgen11 flies lack antennal structures. This phenotype is significantly rescued by fz3G10.
