Comments on Cytology

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.

    In combination with other aberrations

    The z1 In(1)wis eye colour phenotype is suppressed by Df(YS)B4, Df(YL)S6 and Df(YS)S12, and enhanced by Df(YL)G22 and Df(YL)S10.

    NOT in combination with other aberrations

    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.

    Other Comments

    The w gene on the In(1)wis chromosome is influenced by position effect variegation and also regulated by chromosome pairing-dependent z1-mediated repression.
