Genetic mapping information
Comments

Breakpoint 1 was linked to a HindIII-HindIII restriction fragment. The position of the restriction fragment on the reference sequence was inferred by a FlyBase curator.

(Kuroiwa et al., 1985)

Breakpoint(s) molecularly mapped

(Garber et al., 1983)

Deletes sequences to left of a point 100 kb to the left of the proximal breakpoint of In(3R)Hu (Garber et al., 1984).

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.
