80% of ommatidia contain more R7 cells than normal in flies expressing bossScer\UAS.cKb under the control of Scer\GAL4hs.2sev, with an average of 2.7 R7 cells per ommatidium.
Scer\GAL4hs.2sev, bossUAS.cKb has photoreceptor cell R7 | ectopic phenotype, suppressible | partially by cdiUAS.cSa/Scer\GAL4hs.2sev
Co-expression of cdiScer\UAS.cSa partially suppresses the extra R7 photoreceptor cell phenotype seen in flies expressing bossScer\UAS.cKb under the control of Scer\GAL4hs.2sev.
