Figure 4
Estimated population structure from Geneland analyses for the two modal solutions K = 3 and K = 4. Each individual is represented by a thin horizontal line divided into K coloured segments that represent the individual's estimated membership fractions in K clusters. Black lines separate individuals from different geographic areas labelled on the right. Each plot, produced with Distruct [79], is based on the highest-probability run at that value of K. Individuals are arranged based on their origins and sorted with increasing latitude.
