Figure 3A

Relationships among individuals were reconstructed using the neighbour-joining method on a matrix of allele sharing distances (ASDs). Unrelated individuals from four populations are shown: African-American (labelled AfX; n = 20); European-American (labelled EuX; n = 38; Japanese (labelled JpX; n = 10); and Chinese (labelled ChX; n = 10), along with two nuclear family trios (mother, father and child, labelled FXM, FXF and FXC, respectively). This figure shows phylogeny constructed using all 8,525 autosomal single nucleotide polymorphisms. Figure 3B shows phylogeny constructed using the 1,000 highest FST markers. Figure 3C shows the tree of individuals constructed using the 1,000 lowest FST markers. It is notable that the family relationships are still evident in the two trios when using markers like these, which clearly contain no information regarding population differences.
