Figure 8From: Transcriptomic analysis of candidate osmoregulatory genes in the eastern oyster Crassostrea virginicaDistribution of (A) dN, (B) dS and (C) dN/dS ratio values. dN and dS show similar distribution shapes with the number of synonymous substitutions much larger than the number of nonsynonymous substitutions. Most ortholog pairs had a dN/dS ratio below 0.2 indicating a strong role for purifying selection on oyster peptide sequences.Back to article page
