From: Copy number variation signature to predict human ancestry
Identification of unique caCNVs among European, African, and Han Chinese Populations. A) Venn diagram of the 92 caCNVs identified from the pair-wise population comparisons identifies 73 unique caCNVs. B) Scatter plot of the top two principal components using data generated from the 73 unique caCNVs shows good separation of individuals based on ancestry (red square: CEU; yellow triangle: YRI; blue circle: CHB). C) Plot of the misclassification error rate for predicting ancestry using decreasing numbers of the caCNVs identified using ten-fold cross validation analyses of the training set.
