Comments

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

Left limit of break 1 from polytene analysis (FBrf0044420) Right limit of break 1 from inclusion of hat (FBrf0044420) Left limit of break 2 from inclusion of dsx (FBrf0049832) Right limit of break 2 from polytene analysis (FBrf0044420)

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.
