Transposition of jockey and 1.8kb of the sc gene (which contains an enhancer responsible for the development of anterior notopleural bristles) from scD1 into the gypsy element present at the y locus in y2. A small fragment of the gypsy sequence, including the su(Hw) binding region, has been deleted and replaced with the inserted sequence. Insertion into y is in opposite orientation to that of y2#+9.
Body colour: mutant flies have wild-type pigmentation in the body and wings and in the thoracic, leg and abdominal bristles.
Pigmentation of homozygotes is normal.
Revertant.
Taf91, y+2MC has abnormal body color phenotype
y+2MC has phenotype, non-enhanceable by mod(mdg4)ul
sc+2MC, y+2MC has anterior notopleural bristle phenotype, suppressible | partially by zop6
sc+2MC, y+2MC has anterior notopleural bristle phenotype, suppressible | partially by e(y)21
sc+2MC, y+2MC has anterior notopleural bristle phenotype, non-suppressible by Taf91
sc+2MC, y+2MC has anterior notopleural bristle phenotype, non-suppressible by e(y)34
Pigmentation of the thoracic, leg and abdominal bristles is reduced in combination with e(y)11.
Trans-inactivation by mod(mdg4)ul.
