Affected Genes Inferred by Location (0)
    If no genes are listed here, it may be because the affected region is very large. The JBrowse insert above may show an error for the same reason, and other FlyBase tools such as CytoSearch may also fail for large regions. You can contact FlyBase for more help.
    In these cases, there will be no "Export to Hitlist" button to the left.
    Phenotypic Data
    In combination with other aberrations
    NOT in combination with other aberrations

    Does not completely block transvection, shows some reduction of alula when heterozygous with Cbx alleles of Ubx. Causes moderate reduction of pigmentation in posterior segments when heterozygous with Df(3R)Ubx-RS4-8. Causes strong disruption of pairing at BX-C in salivary chromosomes when heterozygous with wild type.

    Selected on basis of ability to suppress transvection in UbxCbx heterozygotes.
