Genetic mapping information

Breakpoint(s) molecularly mapped

Proximal (84C1-3) breakpoint estimated to be at about +26 to +27 kb, based on location of 84C1-2 breaks of T(2;3)Ta1 at +34 kb and Df(3R)Scr2 at +41 kb (Baker and Wolfner, 1988, Genes Dev. 2: 477-89)

Comments on Cytology

    In combination with other aberrations

    Df(3R)dsx2M/Df(3R)Scx2 is pupal lethal. Df(3R)dsx2M/Df(3R)Scx2 mutants also exhibit an apparent failure of body wall muscle contraction during puparium formation.

    Inferred to overlap with: Df(3R)Scx2.

    Inferred to overlap with: Df(3R)Mlp84BP8.

    NOT in combination with other aberrations

    The Df(3R)dsx2M chromosome does not act as a dominant suppressor of telomeric silencing (assayed using the effect of the chromosome on the eye colour phenotype of flies carrying "P{wvar}KR3-2", a stable "brown-red" variant of the P{3'WP-2,wvar}2Lt insertion).

    Males fertile when in combination with αTub84B7.
