Rearrangement breakpoint within Ubx.
Ubx80/Df(3R)P115 clones in T2p or T3p legs show a transformation into prothorax.
Ubx80/Df(3R)P115 tissue in the posterior compartment of the mesothoracic legs shows transformation to the posterior compartment of the prothoracic leg in gynandromorphs.
The frequency of variegated bithorax transformations seen in Df(3R)red-P52 heterozygotes is increased in flies also containing a copy of Ubx80.
