FIG. 2.

Caribbean AGM speciation based on mitochondrial DNA characterization. Cytochrome b sequences (267 bp) were amplified from Caribbean AGMs and compared with those of different species of AGMs from Africa. Sequences originating from different species of AGMs of African origin are color coded: sabaeus in red, tantalus in blue, grivet in orange, and vervet in green. Sequences from Caribbean AGMs are shown in black. Monkeys coded EI are from St. Kitts island; monkeys coded A and B are from Barbados. Cytochrome b sequences from other species of African monkeys are shown in gray. The phylogenetic trees were estimated by the maximum parsimony method. The reliability was estimated from 1,000 bootstrap replicates; only bootstrap values relevant for lineage definition are shown.
