Mean genetic ancestry proportions determined via ancestry informative markers and HLA haplotype origin frequencies for subpopulations defined by reported race/ethnicity or geographic ancestry.

<p>* All individuals have two HLA haplotypes. Multi-origin haplotype classification indicates that one of the individual’s haplotypes is closely associated with one continental origin while the other haplotype is associated with a different continental origin.</p><p>Mean genetic ancestry proportions determined via ancestry informative markers and HLA haplotype origin frequencies for subpopulations defined by reported race/ethnicity or geographic ancestry.</p

African and Amerindian genetic ancestry proportions (a,c) and HLA origin frequencies (b,d) are correlated with the number of grandparents with reported African and Latin American ancestry, respectively.

<p>Genetic ancestry proportions were estimated from AIMs data using Structure and the HGDP reference set. For this analysis, k = 4, reflecting broad continental ancestry. For each subpopulation defined by the number of respondents’ grandparents with Sub-Saharan African/African American or Latin American ancestry, the percentage of individuals with zero, one or two African or Amerindian HLA haplotypes, respectively, was calculated. Individuals reporting one, two, three or four African-ancestry grandparents: n = 4; 4; 2; 21, respectively. Individuals reporting one, two, three or four Latin American-ancestry grandparents: n = 16; 21; 7; 38, respectively.</p
