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

    Phenotype w+. Males rarely survive and survivors are sterile; females are viable. Dp(1;1)w+2, z males are z (Rasmuson, Svahlin, Montell and Olofsson, 1978, Mutat. Res. 54: 33-38).
