Observed and expected heterozygosities of Near Eastern (NEWB) and European (EUWB) wild boar and Iberian (IB) and Mangalitza (MA) pigs¹.

1<p>Far Eastern wild boar and Canarian pigs were not included in this analysis because of insufficient sample size.</p

Multidimensional scaling plot based on genome-wide identity-by-state pairwise distances inferred with PLINK.

Structure-based estimation of the admixture proportions of 83 individuals belonging to ten <i>Sus scrofa</i> populations.

Maximum likelihood trees constructed with TreeMix depicting splits and migration events (m = 1–4) between six <i>Sus scrofa</i> populations: 1, Near Eastern wild boar; 2, Mangalitza pigs, 3, Canarian pigs; 4, Iberian pigs; 5, European wild boar; 6, Korean wild boar.

<p>Edges, whose color ranges from red to yellow depending on the weight of the migration event (measured as the fraction of alleles coming from the parental population), indicate the direction of gene flow between populations. Probabilities associated with each migration event are represented by <i>P</i>-values in bold.</p
