P2036, an allele of Star, enhances the Gl¹ eye phenotype. Scanning electron micrographs of Drosophila eyes. (A) In the wild-type eye, ommatidia are arranged in an orderly fashion. (B) Eyes derived from Gl¹ flies show disorganization in the arrangement of the ommatidia and bristles, giving a `rough' appearance to the eye. (C) The parental line P2036 is not distinguishable from the wild type. (D) Eyes expressing both P2036 and Gl¹ are reduced in size and the general surface of the eye is very rough, showing a dominant enhancement of the Gl¹ rough eye. Genotypes shown: (A) wild type +/+; +/+, (B) +/+; Gl¹/+, (C) P2036/+; +/+, (D) P2036/+; Gl¹/+.
