Fig. 2: Continental genetic ancestry.
From: Genetic ancestry and population structure in the All of Us Research Program cohort
a Genomic PCA with All of Us participants shown in gray and global reference population samples color-coded as shown in the key. Left panels show PC1 versus PC2 comparisons, and right panels show PC1 versus PC3 comparisons, with the percent of variance explained by each PC shown. b Genetic ancestry proportions for All of Us participants stratified by the genetic similarity groups shown in Fig. 1c. Average ancestry proportions are shown above each group, and numbers of participants are shown below each group. The remaining participants are individuals who did not fall into a dense PCA cluster.
