Abstract
The ability to identify the sex of individuals from noninvasive samples can be a powerful tool for field studies. Amelogenin, a nuclear gene proximate to the pseudoautosomal region of mammalian sex chromosomes, has a 6 base-pair (bp) size difference between human X and Y chromosomes that can be PCR-amplified and sized to distinguish male from female DNA. We examined whether this test can be used to identify sex from different DNA sources across a number of nonhuman primate taxa. Using human amelogenin primers, we were able to amplify diagnostic products from the four great ape species tested, but products from five other primate species were not sexually dimorphic.
