T(2;3)bwVDe3;T(2;3)ul10#4/Df(3R)Ubx-RS4-8 animals show significantly less pigment than T(2;3)ul10#4/Df(3R)Ubx-RS4-8 animals.
Shows a weak bxd phenotype when hemizygous. Does not completely block transvection, shows some reduction of alula when heterozygous with Cbx alleles of Ubx. Causes strong reduction of pigmentation in posterior segments when heterozygous with Df(3R)Ubx-RS4-8. Pigment is patchy and varies from animal to animal. Causes very strong disruption of pairing of the BX-C when heterozygous with wild type salivary gland chromosomes.
Selected on basis of ability to suppress transvection in UbxCbx heterozygotes. Breakpoint shown to be in bxd region of BX-C by chromosome in situ hybridization.
89E break spanned by a bxd region clone in in situ hybridization.
