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

    Df(2L)b83d29a/Df(2L)A400 is Pburs-.

    (Davis, 2001.4.23)

    Ts(Y;2Lt)GT2+Ts(YSt;2Rt)A80/Df(2L)b83d29a and Df(2L)TE35B-12/Df(2L)b83d29a animals usually die as pharate adults, escapers have crippled legs and show an "elbow" phenotype. Ts(Y;2Lt)a15+Ts(YSt;2Rt)A80/Df(2L)b83d29a animals usually die as pharate adults, escapers have crippled legs. Df(2L)A400/Df(2L)b83d29a animals do not usually survive to adulthood, escapers have crippled legs and show "elbow" and Pburs phenotypes. Ts(Y;2Lt)el4+Ts(YSt;2Rt)R15/Df(2L)b83d29a animals die as pharate adults with crippled legs. Df(2L)el14/Df(2L)b83d29a animals often do not survive to adulthood, those that do have crippled legs. Df(2L)el16/Df(2L)b83d29a animals do not usually survive to adulthood, escapers have a weak crippled legs phenotype. Df(2L)fn2/Df(2L)b83d29a adults have a weak crippled legs phenotype. Df(2L)TE35B-1/Df(2L)b83d29a adults are wild-type. Df(2L)TE35BC-8/Df(2L)b83d29a animals often do not survive to adulthood, those that do are wild-type. Df(2L)el28/Df(2L)b83d29a and Df(2L)TE35B-6/Df(2L)b83d29a adults have a weak "elbow" phenotype.
