Fig. 3From: Eimeria zuernii (Eimeriidae: Coccidia): mitochondrial genome and genetic diversity in the Chinese yakCodon usage in PCGs of E. zuernii mtDNA. The numbers on the left and right Y-axis scales referred to the RSCU value and the total number of codons, respectively. Codon families were plotted under the X-axis scale and represented by different colors. The codon counts were depicted by the black line graphBack to article page
