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.

    The status of this duplication is unclear. FBrf0004676 claimed it to be a tandem duplication for 1B1--1B2, but molecular analysis by Campuzano et al. (FBrf0043905) did not find any evidence for a duplication.
