FLP-mediated recombination between the FRT sites present in the two progenitor insertions (P{XP}Naprtd09957 and PBac{WH}f03638) has resulted in a tandem duplication of the genomic sequence between the two insertion sites.
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.
