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
    NOT in combination with other aberrations

    T(1;2)dorrev45 males are inviable. Chromosome compaction includes the 2B7-2B18 region and often spreads further, up to section 3C. At 14oC and 16oC in females carrying Df(2R)M41A10, underreplication and heterochromatinization extend to 5D.
