Fig. 1From: Population genetic structure and gene flow of rare and endangered Tetraena mongolica Maxim. revealed by reduced representation sequencingPopulation structure of 120 Tetraena mongolica individuals from 8 different geographical locations. a Cross-validation (CV) errors suggest that the 120 Tetraena mongolica individuals were divided into 2 genetic populations. b Population structure analysis with K = 2, K = 3. Each individual is represented by a vertical bar that is divided by K colored segments representing the likelihood of a membership to each cluster. The population codes are the same as those shown in Table 2Back to article page
