Breakpoint(s) molecularly mapped

(Biessmann, 1985)

Three discontinuities in DNA sequence at coordinates 40.8-41.5, 53.2-55.0 and 63.3-65.5 (FBrf0043479).

Comments on Cytology

Limits of break 1 from polytene analysis (citation unavailable) Limits of break 2 from polytene analysis (citation unavailable) Limits of break 3 from complementation mapping against y (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.
    Phenotypic Data
    In combination with other aberrations
    NOT in combination with other aberrations

    Regularly generates further rearrangements; has produced losses of the duplicated segment, which are accompanied by changes in phenotype from ybl to y-like and a translocation between the tips of X and 2L accompanied by a change from ybl to y+.
