Hepatitis B Annotation. The estimated parameters for the seven different genomic regions of the Hepatitis B virus NC003977 based on the Woodchuck Hepatitis genome J02442 and the Ground Squirrel Hepatitis genome K02715. Here the darker shades refer to the selection acting on one gene only, and the lighter shades are the selection factors for non-synonymous substitutions in both genes. The error in the parameter estimates (one standard deviation) is given in brackets, in units of 10-2. The x-axis delineates the position on the genome.
