Eye phenotype of a dominant Inx2 mutant.
Scanning electron micrograph of a whole fly eye (left) and a close-up of individual facets from an animal of genotype Inx2TA181 / + . The eye appears to be almost completely wild type with the exception of a misplaced interommatidial bristle (iob) marked by an asterisk. Om – ommatidia. Black scale bar = 2μm. The amino acid substitutions underlying the dominant Inx2 alleles are shown here.
