(A) Distribution of the pairwise sum of Identity-by-Descent (IBD) sharing (cM) between four broadly defined BioMe populations, namely; African American (AA), Ashkenazi Jewish (AJ), Hispanic/Latino/a (H/L) and Non-Jewish European American (Non-AJ EA). (B) Sub-continental diversity in self-reported H/L participants in BioMe. Afro-Caribbean participants fall between European (red) and African (blue) continental reference panels, Mexican and Central/South American H/L participants fall between European and Native American (green) reference panels, mainland US-born participants reside on either cline. (C) The tract length distribution of IBD sharing among BioMe populations, normalized by population size. The y-axis represents the proportion population-level sharing (x / (N*(N-1)/2)), where x is the sum of the number of pairwise shared IBD tracts and N is the number of individuals per population. The AJ population exhibits the highest level of population level sharing, followed by Puerto Rican born H/L.
