Grouping Scan analysis.

<p>Sequence fragments of 250 bases incrementing by 100 bases with 100 bootstrap replicates, were used to compare and analyse (a) <i>P.t.troglodytes/P.t.ellioti</i> recombinant FJ98098.1 (b) <i>P.t.ellioti/P.t.troglodytes</i> recombinant FJ98099.1 (c) <i>P.t.schweinfurthii</i> isolate A498266; (d) <i>P.t.troglodytes</i> AM117396 (e) <i>P.t.troglodytes</i> recombinant AB046525 (f) study recombinant <i>Gorilla gorilla</i> HBV sequence (ECO50003); to sequence groups from <i>Gorilla gorilla</i> (red), <i>Pan troglodytes ellioti</i> (blue), <i>Pan troglodytes troglodytes</i> (green), <i>Pan troglodytes verus</i> (yellow), <i>Pan troglodytes schweinfurthii</i> (purple) and human genotype HBV/C (light blue) with respect to A498266. Values >0.5 indicate clustering within the indicated group.</p

Tree Order Scan of HBV sequences.

<p><b>Figure 2(a)</b>. TreeOrder Scan of HBV sequences, indicating positions of individual sequences (y axis) in Phylogenetic trees generated from sequential 250-base sequence fragments, incrementing by 50 bases. Changes in sequence order as a result of changes in phylogeny at the 70% bootstrap level are shown. Sequences are colour coded by genotype and host species, as indicated by the labels in left and right margin: genotype A, purple; B, light blue; C, wine; D, emerald; E, royal blue; F, orange; G, pale green; H, navy; Gorilla, blue (Gor); Chimpanzee, green (Pan); and Woolly monkey (WM-out-group on line 1), red. For comparison the Tree Order Scan has been aligned with scale genome of HBV (top panel). Recombinant sequences are highlighted as by dashed lines; black gorilla/<i>P.t.e</i> ECO50003LIP3, green FJ798099 <i>P.t.e/P.t.t</i>, pink FJ798098 <i>P.t.e/P.t.t</i>, orange AB046525 <i>P.t.t</i> and purple AF498266 <i>P.t.s </i><b>2(b).</b> Tree Order Scan of HBV sequences, indicating positions of individual sequences (y axis) in phylogenetic trees generated from sequential 250-base sequence fragments, incrementing by 50 bases.
