Each insert or deletion event was counted as one variation.
The first, second, and third nucleotide positions in a codon.
Amino acid changes (nonsynonymous changes). Each insert or deletion event was counted as one variation.
Each nucleotide position is counted once based on 90 complete genome alignments.
CG, complete genome; NCR1, noncoding region 1 between the E2 and E5 ORFs; NCR2, noncoding region 2 between the E5 and L2 ORFs; LCR, long control region.
