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

    Heterozygotes are viable and fertile. Heterozygous ovaries have a number of morphological defects; there are fewer terminal filament (TF) stacks at 24 hours after ecdysis to the third instar compared to control flies. There are more TF cells/stack at 24 hours after pupariation compared to control flies and the apical cell population is reduced, leading to a spiral orientation of TF stacks. Epithelial sheath cells often remain adherent to the ovarioles at 48 hours after pupariation.
