Figure 3.

Inference of local ancestry. The plot shows the results of a typical EM run for local ancestry inference of a three-way admixed individual. Each panel shows ancestry allele dosages (y-axis), one for each source population, along the chromosome (x-axis). Black lines in each panel are the true values, and blue lines are estimated mean dosages. Gray bars on top of blue lines reflect ±2 SD of the estimated mean dosages. At each marker, y-values on lines of the same color sum to 2.
