Insertion in the first intron that is common to all four predicted transcripts of jigr1.
jigr1[+]/jigr12205 is an enhancer of visible | adult stage | temperature conditional phenotype of Nnd-1
jigr12205, wg[+]/wgGla-1 has visible | adult stage phenotype
Precise excision of the insertion can revert the mutant phenotype.
