Genetic screen for modifiers of ectopic hairy expression in the eye of Drosophila. (A–D) Light photomicrographs showing dominant suppression of the eye phenotype by gro alleles; weak for MB5 and strong for the null allele MB36. Genotypes are as indicated below. (E) Schematic representation of the screening strategy. F1 progeny homozygous for GMR-Gal4,UAS-hairy and heterozygous for a mutagenized FRT 80B FRT 82B chromosome were scored for the suppression of the eye phenotype. e, ebony; EMS, ethyl methane sulphonate; Gro, Groucho; h, hairy; w, white.
