The mesothorax phenotype is reduced in combination with RpII215Ubl. The dominant wing phenotype is 80% penetrant, and occurs variably within the anterior compartment. UbxCbx-3/Ubx195 transheterozygotes sometimes show transformation of T3a towards T2a.
Phenotype is partially penetrant in heterozygotes, and shows erratic specificity.
Mesothoracic phenotype does not vary in the presence of extra copies of the bithorax complex, or with homologous chromosomes with breaks proximal to the bithorax complex.

The Cbx mesothorax phenotype is reduced in a number of Cbx mutations in combination with RpII215Ubl. This reduction of the Cbx phenotype follows the order: UbxCbx-Hm > UbxCbx-2RM = UbxCbx-2 = UbxCbx-M1 > UbxCbx-1RM = UbxCbx-1 = UbxCbx-3 = UbxCbx-Twt.
