Population structure of 80 NRVs based on 17 markers (K = 2) and graph of estimated membership fraction for K = 2.

<p>The maximum of adhoc measure ΔK determined by structure harvester was found to be K = 2, which indicated that the entire population can be grouped into two subgroups. Different color within group indicates the proportion of shared ancestry with other group which has the same color with the admixture.
