Pc4/Snr1E1 animals have incomplete L3, L4 and L5 wing veins (9%, 42% and 37% respectively) and moderate curling and disruption of the wing along the posterior wing margin. Pc4/brm2 animals have an incomplete L3 wing vein (15%).
The average number of sex comb teeth per first leg Scr2/+ males is not affected if they are also carrying Pc4. The average number of sex comb teeth per first leg Df(3R)Scr/+ males is not affected if they are also carrying Pc4.
The addition of Df(3L)10H, Rpd304556, Rpd3303, Rpd3313 or Rpd3def8 to Pc4 animals more than doubles the average number of ectopic sex comb teeth seen per leg. The addition of Rpd3326 to Pc4 animals partially suppresses the ectopic sex comb teeth phenotype.
AsxP1 strongly enhances the extra sex combs phenotype and abdominal homeotic transformations associated with Pc4. Pc4/+, Df(2R)trix/+ show a darkly pigmented outgrowth from the first thoracic segment, corresponding to a strong posterior transformation of the prothorax to mesothorax.
The formation of extra sex combs on the second and third legs in Pc4/+ flies is dominantly enhanced by Mi-2K1, Mi-21, Mi-2j3D4, Mi-24, Mi-25, Mi-26, Mi-27, Mi-28, Mi-29 or Pcl10. The formation of extra sex combs on the second and third legs in Pc4/+ flies is not enhanced by Trl62, Trl3 or Trls2325.
