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.
    Phenotypic Data
    In combination with other aberrations

    Heterozygotes with T(Y;2)A162, T(Y;3)H135, T(Y;3)H138, T(Y;2)H149, T(Y;2)J165, T(Y;2)P8, T(Y;2)P51, T(Y;2)R93, T(Y;2)B24, T(Y;3)D221, T(Y;3)G45, T(Y;3)G130, T(Y;2)J163, T(Y;3)R78 or T(Y;3)R119 are sterile, heterozygotes with T(Y;2)A77 or T(1;Y)V8 are fertile.

    (Gatti and Pimpinelli, 1983)
    NOT in combination with other aberrations

    Male sterile. Heterozygotes with ks-1S23 or ks-1S24 are sterile.

    (Gatti and Pimpinelli, 1983)
