Detailed Description
	Statement Reference fz[37]/fz[30] show defects in the orientation of the mitotic spindle in dividing pI sensory precursor cells. (David et al., 2005) In fz³⁰/fz³⁷ pupae, the mitotic spindles of dividing sensory organ precursor cells in the developing notum are not aligned with the anterior-posterior axis, but instead are randomly oriented. (Bellaiche et al., 2004) In fz³⁷/fz³⁰ mutant pupae, unlike wild-type, the pI cells exhibit almost no centrosome rotation before spindle formation. Complete rotation values for the spindle are similar to wild-type, however in 7% of mutant pI cells, the spindle rotates in one direction before rotating in the opposite direction, bidirectional movements are not seen in wild-type. The spindle does not line up properly with the pon crescent, leading to defective partitioning of pon. 5% of fz³⁷/fz³⁰ flies have at least one bristle with two shafts and two sockets on the notum. (Bellaiche et al., 2001) Only 47.1 +/- 8.9 % of ommatidia in fz³⁷/fz¹⁵ flies have the correct chiral shape. (Strapps and Tomlinson, 2001) The orientation of projections of R1-R6 axons onto the lamina is normal for those ommatidia that are correctly orientated, and rotated for those ommatidia that are rotated. (Clandinin and Zipursky, 2000) Dendritic development in homozygous mutants is indistinguishable from wild-type. (Gao et al., 2000) Mosaic ommatidia at the boundaries of homozygous clones can show incorrect chirality. In incorrect chiral ommatidia where the mosaic boundary separates the R3/R4 pair, the R4 cell is invariably mutant and the R3 cell is wild type. In these cases the presumptive R3 cell has developed as an R4 cell. The R3/R4 pair can also either both be mutant or both be wild-type in mosaic ommatidia with incorrect chirality. Chirally incorrect ommatidia that have wild-type R3 and R4 cells can occur at any position along the border of the clone, but are predominantly found at the polar side of the clone. Mosaic ommatidia at the boundaries of homozygous clones can show correct chirality. In those ommatidia with mosaicism between R3/R4, the R3 cell is almost always wild type and the R4 cell is almost always mutant. Mosaic ommatidia at the boundaries of homozygous clones are occasionally symmetrical, and in these cases both members of the R3/R4 pair are generally mutant. Expression of fz^hs.sev in a fz³⁷ background in either the presumptive R3 or R4 cell in mosaic ommatidia causes the cell expressing fz^hs.sev to become an R3 cell and the other to become an R4 cell. (Tomlinson and Struhl, 1999) In fz³/fz³⁷ transheterozygotes the socket, shaft and pIIb cells are always localised in the region of the cell in contact with pIIb. The socket cells always occupies an eccentric position. (Gho and Schweisguth, 1998) Rough eye phenotype, facets have lost their normal hexagonal shape and exhibit disarranged bristles. The ommatidial polarity is disrupted due to randomised direction of ommatidial rotation, insufficient degree of rotation and incorrect asymmetry established between R3 and R4 cells. (Zheng et al., 1995) Strong phenotype. (Adler et al., 1990)

Additional Comments
Genetic Interactions
Statement Reference The zone of reversed polarity at the back and behind the anterior compartment of each abdominal segment of stan^Scer\UAS.cUa; Scer\GAL4^ptc-559.1 adults is suppressed by fz³⁷/fz²¹. (Lawrence et al., 2004) When ft⁸ homozygous mutant clones are made in the R3/R4 precursors of fz³⁷/fz¹⁵ mutant flies, The mutant photoreceptor precursor eventually becomes an R3 photoreceptor 61% of the time (50% in wild-type). (Yang et al., 2002) The addition of numb⁷⁹⁶ to fz³⁷/fz³⁰, leads to pupae that have sense organs composed of four cells with two socket cells but devoid of either sheath or neuronal cells. (Bellaiche et al., 2001) fz2^{2-2-2.hs.2sev} does not rescue the tissue polarity defect seen in fz³⁷/fz¹⁵ eyes. fz::fz2^{2-2-1.hs.2sev} does not rescue the tissue polarity defect seen in fz³⁷/fz¹⁵ eyes. fz::fz2^{2-1-1.hs.2sev} does not rescue the tissue polarity defect seen in fz³⁷/fz¹⁵ eyes. fz::fz2^{1-2-2.hs.2sev} does not rescue the tissue polarity defect seen in fz³⁷/fz¹⁵ eyes. fz::fz2^{1-1-2.hs.2sev} significantly rescues the tissue polarity defect seen in fz³⁷/fz¹⁵ eyes, such that 93.3 +/- 5.0 % of ommatidia have the correct chiral shape. fz::fz2^{1-2-1.hs.2sev} significantly rescues the tissue polarity defect seen in fz³⁷/fz¹⁵ eyes, such that 76.5 +/- 6.4 % of ommatidia have the correct chiral shape. (Strapps and Tomlinson, 2001) nmo^P1, fz³⁷ double mutant eyes display a large number of ommatidia that do not rotate at all compared to either nmo^P1 or fz³⁷ mutants alone. (Zheng et al., 1995)
