<p>(a) The incident recombinant genomes are depicted in relation to the HXB2 reference strain. Each colored region represents the predicted parent subtype based on the results from Recombinant Breakpoint Analysis; subtype A1 is shown in red, A2 in pink, C in yellow, and D in blue. (b) The two A2D strains with similar structures are shown compared to the CRF16_A2D reference breakpoints from <a href="http://hiv.lanl.gov" target="_blank">hiv.lanl.gov</a>. The A2D strains do appear to be CRF16_A2D infections, but are not directly linked (see text).</p
