Comments

Genomic sequence encoding the open reading frames of B9d2 and tctn has been replaced by a loxP cassette containing a wGMR.PH marker.

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

    Df(2L)B9d2-tctnΔ mutant flies are viable; the males produce motile sperm and show only slightly reduced fertility compared to controls. No obvious defects are observed in the axoneme or the transition zone of chordotonal cilia on antennae, however sperm flagella do show weakly penetrant ultrastructural defects (broken or disorganized axonemes).
