Evidence of recombination.

<p>A cBrother analysis established the recombinant relationship between the human AstV lineage represented by sequence N.L23513 and the NHP AstV lineage represented by the sequence from BG31. Both the top and bottom panels share a common X-axis representing the position within the trimmed alignment. The top panel represents the posterior probability of ancestral assignment for the corresponding ancestral line at a given position within the alignment. The bottom panel represents the number of crossover points which occur at a given alignment position out of the 1000 samples taken from the MCMC chain.
