Comments on Cytology

The X chromosome segment is inserted into chromosome 2 so close to the centromere that it is not possible to determine in salivary chromosome preparations whether it is inserted in the right or left arm of chromosome 2.

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.
