Roughened external eye morphology, internally most facets are missing R7 and some are missing outer cells. Analysis of mosaic facets reveals a strong requirement of R in R7 and a weaker requirement in R6.
Heterozygotes have rough eyes due to disruption of the normal ommatidial array. Most ommatidia have the R7 cell missing, others an outer photoreceptor missing, ommatidia may be fused and their orientation with respect to each other is random. Secondary pigment cells are also missing. Homozygotes have rough eyes and reduced viability. R1/Df(3L)R-E heterozygotes have a rougher eye phenotype than R1 heterozygotes.
Eyes of R/+ rough, have some large dark facets. Photoreceptor cell 7 frequently absent (Carthew). Male genitalia frequently rotated and male sometimes sterile; viability about 80% wild type. wings spread. Thorax short; acrostichal hairs deranged, some missing; eyes small. homozygous female-fertile. RK1. homozygous semi-lethal
