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.

    Recovered as apparent cn double recombinants from test crosses of dysgenic-type males that were heterozygous for a maternally derived dp b cn bw second chromosome and paternally derived autosomes extracted from natural populations and capable of promoting male recombination.
