Crosses were performed to determine if the Dl or Ser mutations affected the viability of e(r)^27-1. Viability of flies heterozygous for the Dl or Ser mutation was compared to viability of flies carrying two wild-type alleles. Heterozygous females and FM7C males from the crosses were used as controls.

Not all of the vials were scored for FM7C males, so the absolute numbers cannot be compared to those of e(r)^27-1 males, however, the data show that the decrease in viability seen in the Dl e(r)^27-1 males was not a general effect of Dl mutations on all males.
