Fig. 2From: Evolutionary pattern of Macaca fascicularis in Southeast Asia inferred using Y-chromosomal geneY-chromosome phylogenetic tree constructed using the haplotypes of Macaca as represented by the BI analysis. ML analysis (− lnL = 3809.0846) produced identical topology. Numbers on the branches represents support values for the ML and BI, respectively (only support values above 50% are shown). Roman numerical represents Macaca species groupings (I = sylvanus; II = silenus; III = sinica; IV = fascicularis). The species nomenclatures are abbreviated as shown in Additional file 2: Table S2Back to article page
