Presumed to have arisen by a single crossover event in the long arm of the Y chromosome, so that no change should have occurred in the rDNA at the bb locus on the short arm of the Y chromosome.
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.
