  • For each SoxN allele: non-balancer F1 female progeny from arm4/FM7 × SoxN/CyO were crossed to the deficiency stock +/Y; Df(2L)Exel7040/CyO; non-balancer F1 progeny from Tcf2/eyD × SoxN/CyO were crossed to each other. All cuticles from F2-progeny, hatched and unhatched, were mounted for examination. F2 phenotypes do not deviate significantly from numbers expected for the hypothesized double-mutant phenotypic class (18.75% for single mutant, 6.25% for double mutant). Significant deviation for 3 degrees of freedom is> 7.815.
