From: DNA barcoding of the Lemnaceae, a family of aquatic monocots
Relative distribution of all intra- and inter-specific divergence for single or combined markers. (A) rpoC1. (B) rpoB. (C) rbcL. (D) matK. (E) psbK-psbI. (F) trnH-psbA. (G) atpF-atpH. (H) atpF-atpH+ psbK-psbI. × axis is uncorrected p-distance with corresponding increment unit based on variation of each marker. Y axis is the number of occurrences. Barcoding gaps were evaluated with high significance (p < 0.0001) by Median and Mann-Whitney U tests for all markers. Blue bars indicate intraspecific distance and red bars are interspecific distance.
