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.

In this case, the "Export to Hitlist" button at left will also be disabled.
The cytological breakpoints of the inversion, predicted from the Release 5 genomic coordinates of the progenitor insertion sites are 1B5;4D7.
The inversion has been verified by polytene cytology.
