The male offspring of In(1)wis z1 females mated to wild-type males have yellow-white variegated eyes. z1 In(1)wis / z1 w+ females have red-orange or orange-yellow variegated eyes. Introduction of Su(z)2unspecified into z1 In(1)wis flies does not alter the background level of pigmentation (white) but darkens the yellow flecks in the eye to orange or red.
Inversion placing the wis mutation close to heterochromatin. The distal breakpoint is distal to w, and the proximal breakpoint is located proximal to or proximally within the bb locus.
