Comments on Cytology

Carries the tip of 2L and In(2LR)40F;59D4-E1 from In(2LR)bwV1 and the tip of 2R and In(2L)Cy from SM1. Deficient for 21D1-22A3 and duplicated for 60B-D1.

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.
