Inferring fine-scale individual ancestry around the world
(P. Paschou, J. Lewis, A. Javed, and P. Drineas)

The decision tree

We propose small panels of Ancestry Informative Markers (AIMs) that may be used to infer fine-scale individual ancestry around the world based on the Human Genome Diversity Panel (HGDP) genotypic data. At each node of the decision tree we propose various panels of markers that - using a Nearest Neighbors approach - can accurately assign an individual to one of the child nodes. (See also Figure 1 in our manuscript.)
