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

    No effect on In(1)wm4h position-effect variegation.

    Viable in combination with In(2L)b80c2.

    NOT in combination with other aberrations

    Heterozygosity for this deletion suppresses the mutant ovarian phenotype of ovoD2.

    Chromosome has no effect on the physical interaction between tandemly duplicated copies of w+ and z1, and has breakpoints outside the critical region.
