Figure 1.
Admixture proportion correlation versus number of AIMs in set.
Correlation between admixture proportions estimated using AIMs and proportions estimated using genome-wide data, using AIM sets of increasing size (increments of 25) for the Cape Town study group (n = 733). A proportion of the SNPs in each set of AIMs were selected using the multiple -statistic, indicated in each panel as a percentage, while the remaining SNPs were selected using the pairwise
-statistic, as described in the Methods section.

Figure 2.
Barplots of ancestry proportions estimated using genome-wide data and using AIMs.
In the first panel ancestry proportions were estimated using genome-wide data. The admixed study group (sac) is ordered by proportions of African San, African non-San, European, South Asian and East Asian ancestry. In the second panel ancestry proportions were estimated using 96 AIMs. Individuals appear in the same order as in the first panel.

Boxplots of ancestry proportions of the Cape Town study group.
Boxplots of ancestry proportions estimated using genome-wide data and proportions estimated using the panel of 96 AIMs are shown in this figure per source population, for the Cape Town study group (n = 733).
