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.

    X ray induced secondary rearrangements demonstrate that the extent of PEV reduces gradually with a decrease in the quantity of adjacent heterochromatic DNA.
