Figure 2From: Biogeography and evolution of the Carassius auratus-complex in East AsiaNeighbour-joining (NJ) tree based on the control region (CR) sequences. NJ tree of haplotypes detected in Carassius auratus based on the CR sequences of mtDNA. Numbers above the internal branches are bootstrap values (< 50% support). Haplotype numbers are followed by the names of islands or rivers where specimens were collected; the number of diploids, triploids + tetraploids (shaded), and individuals for which ploidy was not determined are shown in parentheses. Roman numerals on the right side of the tree denote clade code numbers.Back to article page
