When expression is driven by Scer\GAL4elav-C155 number of photoreceptors per ommatidium are elevated when compared to progenitor Hsap\HD97QP.Scer\UAS, though reduced compared to wild type. When expression is driven by Scer\GAL4GMR.PF rough eye phenotype of progenitor Hsap\HD97QP.Scer\UAS allele is almost undetectable.
