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

    male fertile male rather inviable has occipital bristles; eyes rough, wings spread, wing veins thickened. Female has occipital bristles; wings straight edged and coarse textured. Female with two duplications occasionally survives and shows extreme spread wings and rough eyes.
