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

    Df(2R)Arp1.Fbf1a/Df(2R)Su(z)2-1.b8 embryos have stiff pigmented hairs resembling Fell hairs between the ventral setal belts of the abdominal and thoracic segments.

    NOT in combination with other aberrations

    Has no effect on the phenotype of dominant ovo alleles.

    Heterozygotes with rdgE1 exhibit absence of a deep pseudopupil after 7 days in constant light.
