Genetic mapping information
Comments

The 1B breakpoint mapped (Garcia Alonso and Garcia-Bellido, 1986) to between the gypsy and Sancho2 of Hw1, in such a position as to be clear of the achaete transcription unit.

Comments on Cytology

Limits of break 1 from complementation mapping against ac (FBrf0043905) Limits of break 2 from polytene analysis (citation unavailable)

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.
