From: Modeling the longitudinal changes of ancestry diversity in the Million Veteran Program
Statistical changes in ancestry diversity in four HARE superpopulations. Each facet per row shows the ancestry proportion for three major continental populations (CHB is an East Asian reference population of Han Chinese in Beijing, China; GBR is a European reference population from Great Britain; YRI is a West African reference population of Yoruba in Ibadan, Nigeria). Birth cohorts are shown across the x-axis and are arranged from oldest (BC1) to most recent (BC5). Black lines connecting colored bars designate significant differences in ancestry proportion between those two birth cohorts (p < 2.0 × 10−4 based on five birth cohorts, five ancestry proportion references, and ten birth cohort pairwise comparisons). All proportions, specific p-values from comparisons, and HARE assignments are shown in Additional file 1: Table S2. AFR African, ASN Asian, EUR European, HIS Hispanic
