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.

    Fedorova

    (Puro and Novitski, 1982)

    Fedorova.

     

    An inversion on 3L of 62;67 was superimposed on the In(3LR)CxD chromosome carrying three inversions: 1) In(3L)D (69D3-E1;70C13-D1), 2) an inversion of 71F;85C, and 3) a three-breakpoint inversion (80;84A;93F - seen as two inversions of 80;84A and 84A;93 imposed on the 71F;85C inversion).
