Genetic interactions between tw and rt. (A) The increased level of tw does not have a significant effect on the phenotype of rt mutants. The following numbers of flies were analyzed for indicated genotypes: males rtP/rt571, 58 flies; males +/Dp(1;Y)y2sc; rtP/rt571, 58 flies; males Act5C–GAL4-25/+; rtP/rt2, 55 flies; males Act5C–GAL4-25/UAS–DmPOMT2; rtP/rt2, 43 flies; females Act5C–GAL4-25/+; rtP/rt2, 78 flies; females Act5C–GAL4-25/UAS–DmPOMT2; rtP/rt2, 28 flies. Error bars indicate standard errors of the mean. The difference between phenotypes of compared male genotypes is small but statistically significant (t-test, P < 0.05). The difference between corresponding females is not statistically significant (P > 0.3). (B) The phenotype of rt mutants is insensitive to the decreased level of tw. The following numbers of flies were analyzed for indicated genotypes: males Act5C–GAL4-25/UAS–twRNAi-39, 138 flies; females Act5C–GAL4-25/UAS–twRNAi-39, 111 flies; males Act5C–GAL4-25/+; rtP/rt2, 38 flies; males Act5C–GAL4-25/UAS–twRNAi-39; rtP/rt2, 48 flies; females Act5C–GAL4-25/+; rtP/rt2, 49 flies; females Act5C–GAL4-25/UAS–twRNAi-39; rtP/rt2, 60 flies. The difference between phenotypes of compared genotypes is not statistically significant (t-test, P > 0.07). Error bars indicate standard errors of the mean.
