Figure 4.

Frequency distributions of three statistical values (weighted FST, population branch statistic (PBS), and the modified PBS (PBS′)) in an ~436.3 kb genomic region containing EGLN1, calculated using the estimated allele frequency data of three population triplets: (a) HNA vs. CLM vs. CEU; (b) HNA vs. CLM vs. JPT; (c) HNA vs. CLM vs. YRI. HNA: highland Native Americans; CLM: Colombians from Medellin, Colombia; CEU: Utah residents with Northern and Western European Ancestry; JPT: Japanese in Tokyo, Japan; YRI: Yoruba in Ibadan, Nigeria.
