The w eye enhancer (Ee), flanked by Scer\FRT sites, is inserted 500bp upstream of a P1\loxP-flanked gypsy\su(Hw)BR insulator followed by the w+mC mini-gene.
Flies from most transgenic lines have high levels of eye pigmentation (in a w[-] background).
w+mC.Scer\FRT-Ee.S-500.P1\loxP-su(Hw)BR, wunspecified has abnormal eye color phenotype, enhanceable by zv77h
su(Hw)V/su(Hw)2, w+mC.Scer\FRT-Ee.S-500.P1\loxP-su(Hw)BR, wunspecified has abnormal eye color phenotype, non-enhanceable by zv77h
w+mC.Scer\FRT-Ee.S-500.P1\loxP-su(Hw)BR, wunspecified has abnormal eye color phenotype, suppressible by su(Hw)V/su(Hw)2
su(Hw)V/su(Hw)2, w+mC.Scer\FRT-Ee.S-500.P1\loxP-su(Hw)BR, wunspecified has abnormal eye color phenotype, non-suppressible by zv77h
