Figure 11.

Box-and-Whisker plot of estimates of mean ancestry contribution for the simulated admixed populations with 100 random subsets of 20 or 50 SNPs from panels consisting of top 1%, 2%, 5%, and 10% of the AIMs. (a) Results for the simulated admixed population from CEU and YRI using random subsets of 20 AIMs. The dashed line indicates the true mean ancestry contribution (70%). (b) Results for the simulated admixed population from CHB and JPT using random subsets of 50 AIMs. The dashed line indicates the true mean ancestry contribution (72%). From left to right different colors indicate results for Delta, F_ST, FIC, SIC, and I_n. The last two sets of the plot (yellow and gray) are the results where markers were ranked by the average rank (AVE) or minimum rank (MIN) of all five measures. For each method (color), the four Box-and-Whisker plots from left to right represent analysis results based on AIM panels consisting of top 1%, 2%, 5%, and 10% of the AIMs. See Additional File 11, Table S5 and Additional File 12, Table S6 for summary statistics of estimation errors.
