Does not completely block transvection, shows some reduction of alula when heterozygous with Cbx alleles of Ubx. Causes weak reduction of pigmentation in posterior segments when heterozygous with Df(3R)Ubx-RS4-8. Causes strong pairing disruption of BX-C when heterozygous with wild type.
Selected on basis of ability to suppress transvection in UbxCbx heterozygotes.
All limits from polytene analysis (FBrf0080101)
