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

    Partial reversion of the AntpNs phenotype. Viable when in combination with AntpB.

    (Duncan and Kaufman, 1975)
    NOT in combination with other aberrations

    homozygous lethal

    Antp P1 and P2 promoters are functional and ectopic activity of promoter P2A is reduced. Southern blot analysis reveals no lesion in Antp, despite the reversion of the Ns phenotype.

    (Talbert and Garber, 1994)

    Not a revertant of AntpNs; this phenotype caused by the lesion in osa.
