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

    Transmission rate of Dp(1;f)J21A through females to progeny is 28%, Df(1)RK2 has no effect on transmission.

    (Cook et al., 1997)
    NOT in combination with other aberrations

    The Fas2-positive longitudinal tracts are positioned farther apart from the midline than normal in mutant embryos.

    (Bhat et al., 2007)

    Flies heterozygous for the deletion do not show a Minute bristle phenotype.

    (Marygold et al., 2007)

    No second site non-complementing phenotype with zipEbr and zipmhc-c6.1.

    (Halsell and Kiehart, 1998)

    Midgut development of mutant embryos is wild type.

    (Bilder and Scott, 1995)

    Hemizygous embryos were examined with polarised light microscopy and antibody staining: muscle pattern abnormal due principally to variably expressed defect in insertion site positioning.
