Polytene chromosomes normal.
Increases the frequency of the trx bithorax-variegated phenotype (partial transformation of T3 to T2, mostly in the anterior compartment) in heterozygous combination with Df(3R)red-P52.
Haltere are transformed to wing and are less than 10% of wing size, dorsal tissue of T3 is incompletely transformed to metanotum, hypopleural plates are incompletely transformed to sternopleural plates, 1-2 hypopleural bristles are still present and the anterior third leg displays a weak transformation to anterior second leg, as seen by the bristle pattern.
