Genetic mapping information
Comments

Lesions identified on physical map of N (Artavanis-Tsakonas et al., 1983, 1984; Grimwade et al., 1985). 3C7 breakpoint of In(1)N76b8 chosen as coordinate 0.

Comments on Cytology

Left limit of break 1 from polytene analysis (FBrf0026367) Right limit of break 1 from complementation mapping against w (FBrf0042381) Limits of break 2 from complementation mapping against N (FBrf0026367)

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.

    Stable N but can regain mutability (N --> N+) by reinversion (Welshons and Keppy, 1981; Welshons and Welshons, 1985). Highly mutable FB elements thought to be cause of the instability (Grimwade et al., 1985)
