Phylogenetic networks of (a) CYBA in Europeans and (b) NCF2 in Europeans (black) and Asians (yellow). The lengths of the branches are proportional to the number of mutations. Only nonsynonymous mutations are shown. The haplotype names correspond to the table of inferred haplotypes in the supplementary material, Supplementary Material online. We only show the names of haplotypes with a frequency >5%. Ancestral haplotypes (inferred as being the human haplotype or median vector most similar to the chimpanzee sequence) are indicated by an arrow. Median vectors are in red.
