Fig. 4From: Patterns of genetic variation in the endangered European mink (Mustela lutreola L., 1761)Summary of the clustering results for European mink populations obtained using STRUCTURE. (a) Detecting the number of populations as a function of the highest posterior probability (mean LnP[D]) over the number of clusters k (k = 4). (b) Each individual is represented as a vertical line partitioned into k segments whose length is related to their membership proportions to each inferred k cluster. The subdivision according to sampling localities (dataset I) or drainage distribution (dataset II) is also specified in the figureBack to article page
