Imprecise excision of the P{SUPor-P}NcKG02994 insertion, resulting in a deletion that extends from 1926bp upstream of the Nc transcription start site to within the Nc intron, 890bp downstream of the ATG codon. The deletion also completely removes the upstream CG6685 gene.
Homozygotes show late larval lethality with melanotic tumours.
"CG6685[4]" animals (Df(3L)DroncZ homozygotes in which Dronc function, but not CG6685 function, is rescued by homozygosity for P{drf}) show late larval lethality with melanotic tumours.
"dronc[d5]" animals (Df(3L)DroncZ homozygotes in which CG6685 function, but not Dronc function, is rescued by homozygosity for P{CG6685+tDa}) show mid pupal lethality.
32.67% of the expected number of Df(3L)DroncZ homozygotes which carry both P{drf} and P{CG6685+tDa} survive to eclosion. The remaining noneclosed animals develop to an advanced pharate adult stage.
