PATERNAL, MATERNAL, AND BIPARENTAL MOLECULAR MARKERS PROVIDE UNIQUE WINDOWS ONTO THE EVOLUTIONARY HISTORY OF MACAQUE MONKEYS (original) (raw)

We report the results of one of the first intrageneric analyses to simultaneously survey mitochondrial, Ychromosomal, and autosomal loci from the same individuals representing the same taxa. Phylogenetic trees were constructed for each of these genetic systems from a pool of 63 macaques, representing all 19 recognized species in this genus, and eight outgroup taxa. The mitochondrial locus analyzed here (1.5 Kb) spans the 3Ј end of 12S rDNA, tRNA-VAL, and the 5Ј end of 16S rDNA; the Y chromosome dataset (3.1 Kb) consists of the genes SRY and TSPY; the two autosomal datasets include IRBP intron 3 (1.6 Kb) and the 5Ј half of C4 ''long'' intron 9 (3.3 Kb). A total of 1.35 million bases were read, revealing 682 variable sites within the genus Macaca. With regard to earlier unresolved issues of macaque evolution, a comparison of topologies reconstructed from each of the three genetic systems suggests:
