Comments on Cytology

Terminal deficiency. The arrangement of the P-element relative to the flanking genomic DNA suggests the involvement of an intermediate dicentric chromosome in the formation of this deficiency.

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.

    Df(4)A6-2a and Df(4)A6-2b are derived from the same male parent and are considered sibling deficiencies and not independent events.
