From: Reintroductions and genetic introgression from domestic pigs have shaped the genetic population structure of Northwest European wild boar

Figure 2

PCA plot of the wild boar and a sample of domestic pigs, indicating genetic variation along the first two eigenvectors. Colours correspond to FigureĀ 1. The 25 recent wild boar x domestic pig hybrids identified by structure (threshold assignment proportion 0.25) are indicated in dark grey and four additional advanced generation hybrids with introgressed pig alleles identified in a previous study [21] are indicated in light grey.
