  1. On the two mouse chromosomes with the greatest number of introgressed sites in our study - chromosomes 7 and 17 - Coal-Map’s performance was significantly better than EIGENSTRAT for both single-causal-locus and two-causal-loci traits (Delong et al. test [33] with Benjamini-Hochberg correction [65]; setwise α=0.05; n=20 for each test). We observed a reduced performance improvement on chromosome 15, which had relatively fewer introgressed sites: the improvement was weakly significant for single-causal-locus traits and not significant for two-causal-loci traits (using the same test)
