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.

    Homozygous lethal because of the dominant markers in the component balancers.

    This is a spontaneous translocation that arose in a In(2L)Cy In(2R)Cy; TM2 stock (FBrf0017412, FBrf0066905). It carries a T(2;3) translocation (32;68) between a second chromosome carrying In(2L)Cy (22D1-2;33F5-34A1) and In(2R)Cy (42A2-3;58A4) and TM2 (61A-C;74;89E1-2;93B;96A).

    (Parks and Cook, 2026.8.6)

    Induced on: In(2L)Cy In(2R)Cy In(3LR)Ubx130.
