Fig. 1From: Genome-wide SNP data unveils the globalization of domesticated pigsGlobal genetic structure of pig populations in this study. Multi-dimensional scaling analysis of pig populations from the five continents. Each point represents breed-average coordinates of eigenvalues of principle components 1 and 2. Points are mainly colored based on geographic origin of breeds; blue Asia, red Europe, green America, yellow Africa, purple Oceania, brown outgroup of Suids, black commercial Breeds; the pig populations in the middle of the graph representing admixed Asian and European ancestries are annotatedBack to article page
