Polytene chromosomes normal.
Homozygous pburspupal1 and transheterozygous pburspupal1/pbursexc mutants show partially expanded or incomplete wings, leg extension defects and abnormal tanning.
The programmed cell death which is seen in wild-type wings during wing maturation after eclosion still occurs in pu1/Df(2L)Exel6035 flies.
Pburspupal1 has phenotype, non-suppressible by su(Hw)2
Pbursexc/Pburspupal1 is rescued by Pburs+t.1886
Pburspupal1 is rescued by Pburs+t.1886
The presence of pburs+t.1886 rescues the defects found in pburspupal1 homozygotes or pburspupal1/pbursexc transheterozygotes.
