bowlScer\UAS.cdCIa driven by Scer\GAL4Dll-md23 gives rise legs with expanded t1 fates manifest in the ectopic sex-combs on distal tarsal segments. In more strongly expressing lines the tarsus become severely distorted and carry sex-comb bristles throughout its length. When bowlScer\UAS.cdCIa is driven by Scer\GAL4klu-G410 ectopic sex-comb bristles are present in t2 and t3.
