Homozygous lethal. When P{P-Sal}Pak3P-Sal is present, the w gene of the P{lacW}Dplac insertion variegates, resulting (in a w- background) in an eye that is mostly white with a few patches of red ommatidia. This P-element-dependent silencing of P{lacW}Dplac is dominantly suppressed by Df(3R)Su(var)3-7-P13.
