eye photoreceptor cell
Heterozygotes have wild-type wings.
S104E has a dominant rough eye phenotype. In a small but reproducible fraction of heterozygotes, either R7 or the outer R1-R6 cells fail to develop.
Df(2R)CX1, S104E has visible | dominant phenotype
S[+]/S104E is an enhancer of photoreceptor cell R7 phenotype of SosJC2, sev6
Df(2R)CX1, S104E has wing phenotype
S104E Df(2R)CX1 double heterozygotes show notching of the distal wing margin.
In a sev6/Y, SosJC2/+ background, the percentage of ommatidia with R7 cells drops in heterozygotes from the 16% of sev6/Y, SosJC2/+ to 0%.
S104E is rescued by Shs.8
