Breakpoint(s) molecularly mapped

(Mariani et al., 1985)

Left breakpoint localized to a 4 kilobase BamHI fragment near the origin of a 160 kb walk (Gunaratne, Matsukhani, Lipari, Liou, Martindale and Goldberg, 1986, Proc. Nat. Acad. Sci. USA 83: 701-05).

Comments on Cytology

Ref: FBrf0063642.

(Mariani et al., 1985)

Left limit of break 1 from polytene analysis (FBrf0042424) Right limit of break 1 from complementation mapping against z (FBrf0063642) Limits of break 2 from polytene analysis (FBrf0042424)

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

    Inhibits transvection.

    (Riesgo-Escovar and Hafen, 1997)

    Homozygotes show slightly variegated eye color (Lewis, 1959) heterozygotes over z are z.
