Heterozygotes often show weak transformation of the second and third legs to first legs, and partial transformation of the fourth abdominal segment to fifth abdominal segment.
Homozygotes almost wild type; weakly temperature-sensitive for leg transformations at 29oC. homozygous viable; leg2, leg3 transformed to leg1 (het)

Duncan.
Selected as: Enhancer of the Pc3/+ phenotype.
The order of severity of segmental transformations seen in adults is: Pcl1/Pcl3 > Pcl1/Pcl4 > Pcl3/Pcl3 > Pcl3/Pcl4 > Pcl4/Pcl4.
