Lethal when heterozygous with T(2;3)bwVDe3 and Df(3R)Ubx-RS4-8.
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.
Selected on basis of ability to suppress transvection in UbxCbx heterozygotes.
Cytology described as 61A-61F/89D-63CD/36CD-21 + 100-90A/63CD-61F/89E1-4/heterochromatin + 60-36CD/heterochromatin. Location of the 89E bands was determined by in situ hybridization of BX-C clones to mutant chromosomes.
