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.

    D. Coulson.

     

    Generated by D. Coulson. Four X-ray induced breakpoints at 29F, 42F, 45A and 58E in CyO resulted in the rearrangement of three chromosomal segments that spanned CyO breakpoints in a way that resembles two transposition events.
