Crosses at the Bloomington Stock Center showed that the chromosome carrying the P{lacW}GmerSH1931 insertion is lethal in combination with Df(2R)BSC783 and Df(2R)BSC784. This maps the recessive lethality to the nine-gene asrij to CG3788 region and strongly suggests it maps to the insertion in Gmer. These results are consistent with the conclusions of Ayukawa et al. (FBrf0219480).
