We developed an inexpensive, fast and reliable PCR method for sex identification of giant panda (Ailuropoda melanoleuca) by using one pair of primers to co-amplify homologous fragments with size polymorphism that located at amelogenin (AMEL) exon 5. In giant panda, a 63 bp deletion in exon 5 of Y-linked allele provides a significant discrimination between AMELX and AMELY, thus the amplification products can be distinguished simply by agarose gel electrophoresis, exhibiting sex-specific banding patterns (male: 237 bp, 174 bp; female: 237 bp). Both blood and feces samples from known-sex giant pandas were successfully amplified. Cross species test also revealed that this method could be applied to other Ursidae species.
