Figure 4From: Phylogeography of Camellia taliensis (Theaceae) inferred from chloroplast and nuclear DNA: insights into evolutionary history and conservationNested cladogram of 17 nrDNA haplotypes across the 21 C. taliensis populations. Circles in colors denote different haplotypes, and the size of each circle is proportional to that haplotype frequency across populations. Each branch between the haplotypes represents a mutational step. The dotted lines indicate independent mutation events converging on a shared haplotype. The squared loops show the nested clades or haplotypes in the network, which were resolved by nested clade phylogeographic analysis (NCPA).Back to article page
