bbN/Df(1)17-87 is a suppressor | partially of visible | progressive phenotype of Hsap\PABPN117ala.UAS, Scer\GAL4Mhc.PU
bb[+]/bbN is a non-suppressor of visible | progressive phenotype of Hsap\PABPN117ala.UAS, Scer\GAL4Mhc.PU
bbN/Df(1)17-87 is a suppressor | partially of wing | progressive phenotype of Hsap\PABPN117ala.UAS, Scer\GAL4Mhc.PU
bb[+]/bbN is a non-suppressor of wing | progressive phenotype of Hsap\PABPN117ala.UAS, Scer\GAL4Mhc.PU
The age progressive wing posture defects (wings up or down) characteristic for flies expressing Hsap\PABPN117ala.Scer\UAS under the control of Scer\GAL4Mhc.PU is not suppressed by combination with either bbN or Df(1)17-87 alone, but when combined with the two together, the frequency of the abnormal wing posture phenotype is significantly reduced.
