Figure 3From: Restricted gene flow at the micro- and macro-geographical scale in marble trout based on mtDNA and microsatellite polymorphismAdmixture analysis using STRUCTURE, in which individuals were assigned on the basis of the most likely K (in this case, K = 2). Populations are numbered from 1 to 11 following the order in Figure 1. Population 12 is a pure brown trout population (Chisone). Each vertical bar represents one individual, partitioned into two segments according to the proportion of marble trout (red) and brown trout (green).Back to article page
