  1. Homozygous dsp1 1females were crossed with either corto 420/TM3 or corto 07128/TM3 males, or with Oregon-R males as controls. The resulting male progeny was scored for two homeotic transformations previously observed in dsp1 1 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.
