Phenotypic Data
In combination with other aberrations
Df(1)109 does not dominantly affect position effect variegation at the Sb locus which is caused by T(2;3)SbV.
Df(1)174 does not dominantly affect position effect variegation at the Sb locus which is caused by T(2;3)SbV.
Position effect variegation (PEV) at the Sb locus caused by T(2;3)SbV is dominantly enhanced by Dp(2;2)Mdh, and suppressed by Df(2R)en-A or Df(2R)en-SFX31.
The position effect variegation of Sb caused by T(2;3)SbV is strongly suppressed by C(1;YL)wmMc in both males and females. This interaction is both dominant and dosage sensitive; one copy of the C(1;YL)wmMc chromosome is sufficient to suppress variegation of Sb caused by T(2;3)SbV, however, two copies of C(1;YL)wmMc produce slightly greater suppression than one copy. The In(1)wm51b and In(1)wm4 chromosomes have similar, although less dramatic, suppressing effects on Sb variegation caused by T(2;3)SbV. T(1;4)wmJ has no clear effect on the variegation of Sb caused by T(2;3)SbV. The T(2;3)SbV chromosome may have a slight suppressing effect on the variegation of w caused by C(1;YL)wmMc and In(1)wm4 in males, but has no clear effect on the variegation of w caused by In(1)wm51b or T(1;4)wmJ.
NOT in combination with other aberrations
Flies carrying one copy of T(2;3)SbV frequently display a mosaic thoracic bristle phenotype, wherein bristles are both short and long; this phenotype that is enhanced by one copy of Su(var)2054 or Su(var)3-96, but unaffected by one copy of HIPP11G3, HIPP13G10, HIPP1Δ37, HIPP1ΔDsR, HIPP1sfGFP.
Mutations of Rm62 increase the number of mutant bristles.
Position-effect variegation and effect of variegation modifiers on expression of Sb in T(2;3)SbV studied.
SbV/+ has mixture of wild-type and Sb bristles. In X/X/Y female and X/Y/Y male, bristles nearly all Sb. In X/0 male, bristles usually all wild type. SbV/Sb and homozygous SbV are lethal. RK1A. weak allele homozygous lethal
