From: Analysis of synonymous codon usage in Hepatitis A virus
A plot of value of the first and second axis of each complete coding region in COA. The first axis (ƒ'1) accounts for 26.98% of the total variation, and the second axis (ƒ'2) accounts for 19.50% of the total variation. A): Each HAV complete coding region was divided by geographical area. B): Each HAV complete coding region was divided by genotype.
