Genetic complementation test of ozDf2. (A) ozDf2 was tested by a standard genetic complementation test to check whether it uncovers spe-19. The ozDf2/spe-19 worms were expected to be sterile, but were fertile. Thus, the deletion complements spe-19 although it is predicted to delete spe-19. (B) This implies that ozDf2 must be a complex deficiency, retaining the spe-19 containing region, within a deletion that surrounds this locus.
