Fig. 2From: Assessing the suitability of mitochondrial and nuclear DNA genetic markers for molecular systematics and species identification of helminthsEstimated cut-off per taxonomic level of the mitochondrial rRNA genetic markers based on ‘K-means’ algorithm for nematodes belonging to Trichocephlida (a), nematodes belonging to Ascaridida and Spirurida (b), nematodes belonging to Strongylida (c), trematodes (d) and cestodes (e). Each colored circle indicates a genetic distance value that was input into the ‘K-means’ algorithm, and the dashed lines indicate the maximum genetic distance for each taxonomic level estimated with ‘K-means’Back to article page
