Coancestry superposed on admixed populations yields measures of relatedness at individual-level resolution
Fig 6
Heatmaps of individual-level coancestry estimates in the merged data set of mainland Indians from IND, and Central/South Asians and East Asians from HGDP.
Each cell represents the estimated coancestry between a pair of individuals, with warmer colors indicating higher values. (A)–(C) show estimates from the observed genotypes using the Ochoa–Storey (OS) method, the super admixture method, and the standard admixture method, respectively. (D) shows estimates from bootstrap re-sampled genotypes using the OS method, with antecedent allele frequencies simulated under a double-admixture approach. (E) shows estimates from bootstrapped re-sampled genotypes using the OS method, with antecedent allele frequencies simulated using the NORTA approach.
