Mismatch distributions and Bayesian skyline plot of 5<i>i</i> sequences.

<p>The mismatch distribution is based on the complete <i>G</i> gene sequence and is calculated separately for the following: 152 <i>5i</i> sequences from Denmark, Germany, and the United Kingdom, collected between 2000 and 2011; and 137 Danish <i>5i</i> sequences from 2000 to 2009. <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0164475#pone.0164475.t001" target="_blank">Table 1</a> lists the respective values of the raggedness index (r), nucleotide diversity (PI), Tajima’s D, and Fu’s Fs of each dataset. The Bayesian skyline plot shows changes of the 5<i>i</i> population size between 2000 and 2009. The plot was generated using 137 Danish 5<i>i</i> sequences (complete <i>G</i> gene sequence). X axis: time in years, Y axis: population size. The middle solid line is the median estimate, and the area between the blue lines shows the 95% highest probability density (HPD).
