Right break is just to the left of 1C1.

(Lefevre, 1970)

Left limit of break 1 from polytene analysis (FBrf0063629) Right limit of break 1 from complementation mapping against y (FBrf0063629) Limits of break 2 from polytene analysis (citation unavailable)

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.
