P{lacW} insertion in an alternative exon in the 5' UTR.
Homozygotes and rin1/rin2 flies are viable and show a mild rough eye phenotype. Homozygous eyes show defects in both photoreceptor recruitment and ommatidial polarity. Many ommatidia have fewer than the wild-type complement of 8 photoreceptors and some have extra photoreceptors. Both inner and outer photoreceptors can be affected. Many mutant ommatidia with the normal complement of photoreceptors show polarity defects; both the degree and direction of rotation and the chirality of the ommatidia can be affected. The recruitment and polarity defects are evident in third larval instar imaginal discs.

The extra R7 photoreceptor cells seen in flies carrying sevS11.T:Hsap\MYC are reduced to an average of 2.71 +/- 0.23 R7 photoreceptor cells per ommatidium if the flies are also carrying rin1. 18.7% of ommatidia have an R7 cell in sev6; SosJC2 flies. This partial rescue of sev6 by SosJC2 is relieved by rin1; 13.9% of ommatidia have an R7 cell in sev6; SosJC2/+ ; rin1/+ flies.
28.7% of ommatidia have an R7 cell in sev6 ; SosJC2 flies. This partial rescue of sev6 by SosJC2 is relieved by rin1 or rin2; 13.9% and 18.2% of ommatidia have an R7 cell in sev6 ; SosJC2/+ ; rin1/+ and sev6 ; SosJC2/+ ; rin2/+ flies respectively.
Selected as: a modifier of the svp2.sev eye phenotype.
The rin1 homozygous phenotype and the dominant suppression of the svp2.sev eye phenotype are revertable on excision of the P-element.
