Figure 4From: Reintroductions and genetic introgression from domestic pigs have shaped the genetic population structure of Northwest European wild boarMap of the study area indicating identified clusters. Country borders are indicated by black lines, forests are indicated in soft green and inland water features in light blue. Dots indicate wild boar sampling sites. The size of the dot is relative to the sample size. The colours indicate genetic clustering by structure and correspond to other Figures. Hybrids identified by structure (domestic cluster assignment proportion >0.25) are indicated in grey.Back to article page
