At these higher temperatures the di/di vgp/vg females graded phenotypically "notched" to "; The di gene had lowered the pattern threshold some 12° in the females and had lowered it so far in the males that only the full-wing pattern grade was produced throughout the viable temperature range. SHIFTS IN THE CRITICAL TEMPERATURE The di mutation arose in an inbred homozygous vg stock and consequently the di vg genotype differed from this inbred vg strain only in the allele present at the di locus. The original vgp mutant arose in a culture of black vestigial flies. This mutant had been backcrossed for many generations to the inbred vg stock. This produced a vgp line differing from the inbred vg strain by only the allele at the vg locus. Therefore, these three genotypes differed only by known alleles at the vg and di loci. Consequently the introduction of di into this backcrossed vgp stock.
