Genetic mapping information

Breakpoint(s) molecularly mapped

3.0 to 4.4kb DNA is deleted in the neighbourhood of the first chromosome breakpoint.

X breakpoint between left breakpoints of In(1)sc9 and In(1)sc7 (Campuzano, Carramolino, Cabrera, Ruiz-Gomez, Villares, Bononat and Modell, 1985, Cell 49: 327-38).

Comments on Cytology

Cytology inferred from genetic results.

Left limit of break 1 from polytene analysis (FBrf0042024) Right limit of break 1 from complementation mapping against sc (FBrf0042024) Limits of break 2 from polytene analysis (FBrf0047276)

    In combination with other aberrations

    When males with Dp(1;1)Co are crossed with T(1;2)scS2 females, and somatic clones are induced (in the wing disc) with a FRT site at 18A, clones with cells containing 4 copies of dm (2 endogenous and 2 from the tandem duplication in Dp(1;1)Co) and heterozygous for RpL19 (due to missing one copy of RpL19 on Ts(1Lt;2Lt)scS2). These clones are unable to out-compete surrounding cells and are eliminated.

    NOT in combination with other aberrations

    Homozygous females show an almost complete loss of tergite chaetae.
