(A) Heatmap of the European individuals using the molecular relationship matrix, computed using all available autosomal single nucleotide polymorphisms (SNPs). (B) Heatmap of the Asian pigs. In Europe, breed codes are DU, Duroc; IB, Iberian; LR, Landrace; LW, Large White; MG, Mangalitza; PI, Pietrain; and YU, Yucatan minipig. In Asia, breed codes are BX, Bamaxiang; HT, Hetao; LA, Laiwu; LU, Luchuan; MI, Minzhu; MS, Meishan; ST, Sichuan; TT, Tibet; WU, Wuzhishan; and YT, Yunnan. Colors are used to differentiate among the populations: ASDM (Asian domestic, blue), ASWB (Asian wild boar, purple), EUDM (European domestic, green), and EUWB (European wild boar, dark red).
