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.

    Hybrid daughters (from a cross of D.melanogaster females to D.simulans or D.mauritiana males) that carry two D.melanogaster X chromosomes are lethal. This lethality is partially suppressed by one copy of D.melanogaster Df(1)ras203.

    (Barbash et al., 2000)

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