      XX dsx19/Df(3R)dsx15 flies do not show any male-specific courtship when paired with mature virgin females. 9% of XY dsx19/Df(3R)dsx15 flies show male-specific courtship when paired with mature virgin females.

      (Taylor et al., 1994)

      Sex specific neuroblasts fail to undergo any postembryonic divisions in male or female larval nervous systems.

      (Taylor and Truman, 1992)

      Dorsal musculature does not undergo sexual transformation.

      (Taylor, 1992)

      Homozygous males and females are transformed into sexually indistinguishable intersexes.
