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

    Df(1)rb5/T(1;2)biD2 viable Df(1)rb5/T(1;3)biD1T viable

    (Pflugfelder et al., 1990)
    NOT in combination with other aberrations

    In(1)ombH31/Df(1)rb5 adults have reduced sleep, impaired optomotor response and failure to increase fixation on single-objects due to flickering, unlike controls.
