Brownish-red eye. RK1.
awdK, pn3 has lethal | second instar larval stage phenotype
pnhs.4 fails to rescue the lethal interaction of pn3 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.
