Associated with: hhrJ413. The P{PZ}hhrJ413 insertion is identified as an allele of hh on genetic grounds as well as an allele of CG31457 on molecular grounds (it is within the CG31457 transcription unit).
The rJ413 chromosome may carry 2 separable insertions, one within CG31457 and one 5' of hh; an alternative explanation is a single insertion associated with a 14.6-kb deletion between these 2 locations.
