P-element insertion within codon 62, provides an in-frame stop codon 4 amino acids into the inserted sequence.
Homozygous larvae develop normally.
pnhs.4 fails to rescue the lethal interaction of pn77C33 with awdK. pnhs.3 does rescue the lethality (with or without heat shock) and male progeny are recovered. Eye colour of P{HS-PN+4} transformants remains pn even after several heat pulses, P{HS-PN+3} transformants (without heat shock or with one or numerous heat shocks) exhibit wild-type colouration.
