chm	GENE	21	7.2 cM	Starr et al., 2004	Starr CJ et al. (Proc. Natl. Acad. Sci USA 2004) mapped the mutant phenotype  ... Starr CJ et al. (Proc. Natl. Acad. Sci USA 2004) mapped the mutant phenotype chm identified in the ru848 line to LG 21. The phenotype cosegregated with z4425. Further characterization with additional markers revealed a second marker z10960 that was 7.2 cM distant on the other side of the mutation. Genotyping of 2000 mutant larvae revealed that there were only three recombinants between z10960 and chm while there there were 225 recombinants between z4425 and the mutant phenotype. Analyses of BACs containing z10960 revealed the presence of two genes dacha and chm in the region. Subsequent experiments revealed the presence of a nonsense mutation in the chm gene to be responsible for the mutant phenotype.
