Fig. 3. Dhc alleles also interact with Star. (A) The S¹ allele generates a dominant, mild, rough eye phenotype with slightly abnormal ommatidia. (B) Dhc^1-1 dominantly enhances the S¹ eye phenotype. The eyes are narrow, small and the eye surface is rougher. Dhc^1-1/+ by itself does not have any dominant phenotypes. (C) S¹ and Gl¹ interact to enhance the rough eye. (D) Dhc^1-1 further enhances the S¹-Gl¹ eye interaction. Wing phenotypes are also produced (see supplementary material Fig. S1). Genotypes shown: (A) S¹/+; +/+, (B) S¹/+; +/Dhc^1-1, (C) S¹/+; +/Gl¹, (D) S¹/+; Dhc^1-1 +/+ Gl¹.
