Arose during a P{Δ2-3} mutagenesis of the P{PZ}ap41F chromosome which carries ap41F. Southern analysis indicated that P{PZ}ap41F is precisely excised in this allele. It is suggested that the P{PZ}ap41F element excised, reinserted in the 5' end of ap from where it then imprecisely excised, to create the deletion of the 5' ap exon. Four independently derived alleles (apP44, apP22, apP33 and apP39) share these properties.
