Homozygous dsp11 females were crossed with either corto420/TM3 or corto07128/TM3 males, or with Oregon-R males as controls. The resulting male progeny was scored for two homeotic transformations previously observed in dsp11 mutants: (i) transformation of T1 leg into T2 leg monitored by the size of the sex comb, (ii) transformation of segment A6 into segment A5 as revealed by the presence of bristles on A6 sternites.
