Sequence and phylogenetic analyses of A3H in African green monkeys. (A) The evolutionary relationship among 80 full-length AGM A3H genes was inferred by Bayesian MCMC phylogenetic reconstruction. The red asterisks mark nodes that have a posterior probability of >0.5. The colored boxes indicate the subspecies of origin (red, vervet; yellow, sabaeus; blue, tantalus; and green, grivet). The blue asterisks mark cloned haplotypes, numbered 1 to 11 on the right. The arrow marks divergence of the phylogenetic tree between two clades. (B) Numbers of AGM individuals carrying genes encoding haplotypes 1 to 11, color coded by subspecies, similar to A3H phylogeny.
