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.

    Isolated in Madison, USA.

    (Brittnacher and Ganetzky, 1989)

    The chromosome carrying both In(2LR)SD72 and In(2R)NS is referred to as 'SD-72'. 'SD-72' was isolated from a natural population in Madison, Wisconsin in 1956.

    (Hiraizumi, 1989)

    Associated with: In(2R)NS. The chromosome carrying both In(2LR)SD72 and In(2R)NS is referred to as 'SD-72'.

    (Brittnacher and Ganetzky, 1983)

    The chromosome carrying In(2LR)SD72 also contains In(2R)NS, and is referred to as 'SD-72'.

    (Ganetzky, 1977)

    Associated with: SD-72.
