Genetic mapping information
Comments

Breakpoint(s) molecularly mapped

(Ruiz-Gomez and Ghysen, 1993, Campuzano et al., 1985, Carramolino et al., 1982)

Breakpoint between DNA coordinates +5.6 and +4.7 (Campuzano et al., 1985). 0 is an arbitrarily chosen EcoRI site in the scĪ² segment of ASC; positive values to the left (Carramolino, Ruiz-Gomez, Guererro, Campuzano and Modolell, 1982, EMBO J. 1: 1185-92).

Comments on Cytology

Left break irreconcilable with Muller's genetic evidence (FBrf0003098) that the left break of In(1)sc9 is to the right of that of In(1)sc4.

(Lindsley and Grell, 1968)

Left limit of break 1 from polytene analysis (citation unavailable) Right limit of break 1 from polytene analysis (FBrf0042024) Limits of break 2 from polytene analysis (FBrf0042024)

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.
