Flies carrying Adh+tS in an Adh- background show a high survival rate on medium supplemented with 0, 3, 6 or 9% ethanol, with an average survival rate of 89% on the medium containing 9% ethanol. These flies show a strong preference for oviposition on ethanol-containing medium, as do D.melanogaster flies carrying Daff\Adh+tAA1 in an Adh- background.
P1\cre-mediated excision of w+mC and Daff\Adh+tAA1 leaves Adh+tS flanked by an Scer\FRT site on one side and a P1\loxP on the other. Exists in clones, not reported as being germ-line transmitted.
