Fig. 5From: The genetic variation of Angiostrongylus cantonensis in the People’s Republic of ChinaDistribution of haplotypes determined by ITS among the clades inferred by cox1 genes. The top chart is the frequency distribution of haplotypes, and the bottom bar chart indicates the distribution among different clades (denoted by letters). Each column represents one haplotype. The last column denotes all other haplotypes with a frequency of 1Back to article page
