Comments on Cytology

Generated by irradiation of C(1;Y)6, In(1)sc29 to delete most of the X chromosome. The proximal breakpoint lies in X heterochromatin and the distal breakpoint likely lies in 12A. The 12B4,5, 12C1,2 and 12C4,5 doublet bands are clearly present. The 12B1,2 doublet appears to be tightly juxtaposed to the chromocenter.

(Cook, 2008.12.11)

The structure of Dp(1;Y)y+g+ is: X tip to 1A6-1B1 | 13A2-5 to 12A | X heterochromatin | YL - Y centromere - YS tip.

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.
