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.

    In combination with other aberrations
    NOT in combination with other aberrations

    It is proposed that the inversions carried by SD chromosomes from nature act to eliminate recombination and thereby balance the distorting elements of the SD complex.

    (Golic, 1990)

    Lethal and female and male sterile when homozygous.

    Notes on Origin
    Discoverer
     

    Associated with: In(2R)NS. The chromosome carrying both In(2R)SD5 and In(2R)NS is referred to as 'SD-5'.

    (Brittnacher and Ganetzky, 1983)

    The chromosome carrying In(2R)SD5 also contains In(2R)NS, and is referred to as 'SD-5'.

    (Ganetzky, 1977)

    Associated with: SD-5.
