Table 2 Embedded Image for both methods, Predefined-Population and Ancestry-Estimation. Full/Full: Full-data allele frequencies and full-data ancestry proportions from STRUCTURE runs with 791 loci. Full/CODIS: Full-data allele frequencies from STRUCTURE runs with 791 loci and CODIS ancestry proportions from STRUCTURE runs with 13 CODIS loci. CODIS/CODIS: CODIS allele frequencies and CODIS ancestry proportions from STRUCTURE runs with 13 loci. Best-Specified: Allele frequencies from the assumed population to which the individuals and siblings belong. Second-Best-Specified: The second-highest distinguishability value from each column of Table 1, assuming the allele frequencies from the second-best assumed population. Third-Best-Specified: The third-highest distinguishability value from each column of Table 1, assuming the allele frequencies from the third-best assumed population. Fourth-Best-Specified: The lowest distinguishability value from each column of Table 1, assuming the allele frequencies from the fourth-best assumed population. Embedded Image values are calculated using Equation 5 and the distributions plotted in Figures 1 and 3
