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.

    reciprocal translocation between F(3L) and F(3R). Replacement of the centromere regions with that of a normal chromosome by double recombination converts the translocation into a pericentric inversion.
