SNPs output display from chromosome 22 for population CEU, CHB and YRI. We have identified a set SNPs on chromosome 22 which we want to investigate the ancestry informativeness of the SNPs among three populations CEU, CHB and YRI. Using MI-MAAP, we compute LEI measure for the desired set of SNPs. The SNP rs2294368 has the highest LEI value (0.78) as it exhibits relatively large allele frequency differences among the three populations (CEU: 0.79, CHB: 0.17, and YRI: 0.99), which suggests that it is the most informative SNP among the SNPs under consideration to be ancestry informative
