Summary on the nature, incidence, and impact on codons of minor variants across consensus genomes of HK PRRSV strains.

*: percentage of codons (out of the total number of codons) in the coding region with at least one minor variant.
+: percentage of minor variants (out of the total number of variants) capable of causing an amino acid change in their respective consensus codons.
∧: percentage of codons with variants (out of the total number of codons with variants) capable of causing an amino acid change in their respective consensus codons.
Sn: Shannon entropy.
