Fig. 3From: Molecular and phenotypic distinction of the very recently evolved insular subspecies Mus musculus helgolandicus ZIMMERMANN, 1953Population analysis based on STRUCTURE. Clustering of 221 individuals from 9 Mus musculus populations assuming K = 2-7 clusters. The optimal number of clusters is two, the mean (across replicate runs) log likelihood for K = 2 was (-18374.19). Each individual is represented by a column divided into K colors with each color representing a cluster. Different populations are separated by a black line and are labeled below the figure by sample locations and above the figure by geographic regionBack to article page
