Comments on Cytology

One break occurred to the right of the 17E1-17E2 doublet, and the other break probably occurred to the left of the distal 16A1-16A2 doublet of the f[-] progenitor chromosome.

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.
