Comments on Cytology

The 2L breakpoint lies within DS00501. This region is near the telomere, appears to be euchromatic and is approximately 20kb from centric or centromeric heterochromatin. Neocentromere-containing fragments are not recovered from Dp1187-8-23 after γ-irradiation.

(Maggert and Karpen, 2001)

Translocation breakpoint on the X chromosome is at y.

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.
