Cluster and phylogenetic tree analysis. A: Cluster analysis. The phylogenetic tree on the left side is obtained from Frantz et al. [31] and the cluster tree on the right side is obtained by cluster analysis using the actual CN of CNVRs from different populations. The branch length does not correspond to the evolutionary distance. B: NJ-Phylogenetic tree obtained by using the pairwise difference based on SNPs (Abb. see Table 1). C: NJ-Phylogenetic tree obtained by using the pairwise CNDs of all possible pairs for CNVRs overlapping ORs (Abb. see Table 1).
