From: Evolutionary and genetic analysis of the VP2 gene of canine parvovirus
a CoA analysis based on RSCU of 424 CPV VP2 genes. The most frequent codon is represented by circles and the rarest codon is represented by triangles. The remaining codons are represented by squares. b Evolutionary rate of the CPV VP2 gene. Each evolution rate represents the substitution numbers of each sequence compared with the earliest sequence (sub./site/year). The South American clades are represented in orange, the Asian clades in light blue, the North American clades in red, the European clades in dark blue, and the Oceania clades in pink
