Ancestry values and p -values of association tests. The top figures plot recorded and estimated MKK ancestry values of 500 cases (a) and 500 controls (b). Individuals are sorted by their true MKK ancestry values. The bottom figures plot the negative of the base 10 logarithm of p-values of allele-based χ2 tests (c) and structured association tests (d) between 500 cases and 500 controls at 2000 markers.
