Insertion of 6.5kb of DNA into the gypsy element present in the y2 progenitor allele, replacing the central part of the gypsy element. The inserted DNA is flanked by the intact gypsy 3' LTR at the distal end and by approximately half of the gypsy 5' LTR at the proximal end. The inserted DNA contains a jockey element and a 1.8-kb fragment of the sc locus representing the whole segment between gypsy and jockey in the scD1 mutation. The 1.8kb sc fragment contains an enhancer responsible for the development of anterior notopleural bristles. Insertion into y is in opposite orientation to that of y+2MC.
