Genomic Southern blotting demonstrate that the Bar breakpoints within 16A1--16A2 span a 59 kb region with BM1 being the most distal and B58l being the most proximal.
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.
