图2 基于110,451个SNPs利用最大似然法构建的恩克斯堡岛阿德利企鹅的种群遗传结构。(a)交叉验证错误率分布; (b) K = 2; (c) K = 3。图中每一竖条为1个个体, 用颜色表示每个个体基因组中不同祖先所占的比例。

Fig. 2 Based on 110,451 SNPs, the population genetic structure of Adélie penguins was constructed by maximum likelihood method. (a) Distribution of cross-validation errors; (b) K = 2 and (c) K = 3, each vertical bar represents an individual, and the colours show the proportion of ancestry assigned to each of the clusters.
