Comments on Cytology

Ref: FBrf0020681. The third chromosome breakpoint apparently marks the eg locus.

(Puro, 1982)

The break in 2L is to the right of the heavy bands in 33D, probably between the doublets 33D3-33D4 and 33E3-33E4. The break in 3L is to the right of 79A3-79A4 but to the left of 79B1.

(Puro and Arajarvi, 1969)

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.
