Figure 5.

The Pcf11 deletion and duplication mutations show dosage effects on white-apricot (w^a). The eye color indicates the expression level of w^a. The genotypes of the eyes are briefly indicated (“EMS-2” denotes “Inr-a^EMS-2”). One copy of Pcf11 (“Pdel-1/+” in panel A and “EMS-2/+” in panel B) produced the strongest color and three copies (“Pdup-3/+” in both panels A and B) produced the weakest color. When the deletion or the mutation were combined with the duplication, the eye color was largely restored to the wild-type (“Pdel-1/Pdup-3” in panel A and “EMS-2/Pdup-3” in panel B compared with “+/+”).
