Genetic mapping information
Comments

Breakpoint 2 was mapped to an EcoRI-EcoRI restriction fragment. The position of the restriction fragment on the reference sequence was inferred by a FlyBase curator.

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.
