Detailed Description
Statement
Reference

Flies carrying Su(var)3-7+t6.5 show a decrease in crossing over between kni and pp.

Enchances the position effect variegation at the w locus caused by In(1)wm4 and Tp(3;Y)BL2 and seen in the insertion line P{hsp26-pt-T}39C-12, and enhances the position effect variegation at the y locus caused by Dp(1;f)1187, when expressed in a Su(var)3-7+ background. The suppression of variegation at the w locus caused by In(1)wm4 seen in Su(var)2055 flies is partly reduced if the flies are also carrying Su(var)3-7+t6.5.

Flies carrying three copies of Su(var)3-7+ (made using Su(var)3-7+t6.5) show variegation in w+ expression from the P{lacW}ciDplac insertion. Flies carrying three copies of Su(var)3-7+ (made using Su(var)3-7+t6.5) show variegation in w+ expression from the P{hsp26-pt-T}2-M010.R insertion. Flies carrying three copies of Su(var)3-7+ (made using Su(var)3-7+t6.5) show no variegation in w+ expression from the P{lacW}3-76a insertion. Flies carrying three copies of Su(var)3-7+ (made using Su(var)3-7+t6.5) show reduced w+ expression from the P{lacW}ciDplac insertion carried on either T(2;4)DB57A or T(2;4)DB47F compared to flies carrying two copies of Su(var)3-7+, but the w expression is uniform and is not variegated. Flies carrying three copies of Su(var)3-7+ (made using Su(var)3-7+t6.5) show enhanced variegation of w expression from the P{lacW}50C.x7 array.

Rescues the enhancement of variegation of In(1)wm4.
