The posterior femurs of Ubx regulatory mutants. (a) T3p from a fly carrying abx1/Df(3)Ubx109 displays ectopic trichomes in the dorsal anterior compartment (arrowhead, compare with Fig. 2c). (b) T3p of a pbx2 homozygote displays a stripe of ectopic trichomes proximally (arrowhead) and distally. Naked cuticle is observed dorsally and ventrally to the ectopic proximal trichomes. (c) The distribution of naked cuticle on T2p of a pbx2 homozygote is approximately equal to the ventral naked cuticle on T3p (b). (d) T3p of a fly carrying abx1bx3pbx1/Df(3)P2 displays a trichome pattern that is approximately a composite of the abx and pbx patterns, with a naked patch of cuticle only on the posterior proximal surface. (e) T2p from a fly carrying CbxTwt/Df(3)P2 displays a wild type distribution of trichomes.
