Genetic mapping information
Comments

Breakpoint(s) molecularly mapped

(Campuzano et al., 1985, Carramolino et al., 1982)

Breakpoint between DNA coordinates +55.7 and +54.3 (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

Cytology inferred from genetic identity with In(1)sc8.

(Lindsley and Grell, 1968)

Limits of break 1 from polytene analysis (FBrf0039957) Limits of break 2 from polytene analysis (citation unavailable)
