Figure 3From: Single mitochondrial gene barcodes reliably identify sister-species in diverse clades of birdsLevels of intraspecific and interspecific distances of sister-species of birds. a) Frequency distribution of K2P intraspecific and interspecific genetic distances between sister-species. b) Frequency distribution of the ratios of K2P interspecific: intraspecific distances in sister species of birds.Back to article page
