Fig 1. Phylogenetic relationships among macaques based on Alu elements.

Fig 1

(A) PCR amplification analysis of Alu insertion polymorphisms in Macaca. The locus Alu 10 is an Alu insertion specific to the sinica group. The locus Alu 27 is an Alu insertion shared by the sinica and the arctoides groups. The locus yb1-mb-53 is an Alu insertion shared by the fascicularis and the mulatta groups. The locus MS-b1-174 is an Alu insertion clustering the sinica/arctoides and the fascicularis/mulatta lineages. (B) Macaque phylogenetic tree derived from 84 Alu insertion loci polymorphisms. The amplification patterns of the Alu insertions were used to construct a Dollo parsimony tree of macaque phylogenetic relationships using P. hamadryas as outgroup in PAUP*4.0b10. The numbers above the branches indicate the percentage of bootstrap replicates (1000 iterations) producing trees including that node. The numbers below the branches indicate the number of unambiguous insertions supporting each node.
