Shared genome ancestry in Plasmodium simium samples from monkeys and humans inferred by identity-by-descent (IBD) analysis. (A) Frequency distribution of the pairwise proportion of shared genome-wide ancestry between P simium samples. Pink bar segments represent pairwise comparisons of samples from the same vertebrate host (either humans or monkeys), whereas gray bar segments represent comparisons between different host types. (B and C) Parasite relatedness networks. Edges connect parasite pairs with shared ancestry ≥20% (B) or ≥50% (C) and unconnected samples are omitted. Edge thickness is proportional to the IBD fraction.
