Figure 2. Deficiency screen for dominant modifiers of the dNf1 growth defect.

Isogenic 1^st and 2^nd chromosomes deficiencies from the Exelixis, DrosDel and Bloomington Stock Center collections were tested for their ability to alter dNf1 female pupal size. Crossing schemes to generate Df(1)/+; dNf1^E2 (A) and Df(2)/CyO; dNf1^E2 (B) screening stocks. The tubby-marked TM6B 3^rd chromosome balancer allowed the selection of dNf1^E2 homozygotes for measurements. (C) Examples of deficiencies that suppress or enhance the dNf1 size defect. Scale bar = 1 mm.
