Fig. 2From: Population genomics reveal rapid genetic differentiation in a recently invasive population of Rattus norvegicusPopulation structure and genetic relationships among brown rat populations. a Genetic structure of the 50 individuals from the introduced and native populations with ADMIXTURE. The colours in each column represent the ancestry proportion, with presumed group sizes from K = 2 to K = 6. b Scatter plot of principal component 1 versus principal component 2 (PC1 vs. PC2) for all populations. c Phylogenetic tree with Rattus rattus as an outgroup. Group IDs correspond to those in Fig. 1Back to article page
