Deficiency complementation analysis is consistent with the lethality of the line being associated with the insertion. However, since the insertion lies within a dicistronic transcript that encodes the CG33785 and CG33786 open reading frames, the lethality can not yet be conclusively mapped to a single open reading frame from these results. Thus l(2)k02206k02206 (representing the lethality of the chromosome) has been kept as a separate allele in FlyBase for now.
