Abstract: | Molecular sexing is a key component in the investigation of wild populations. In this study, we developed a fast, accurate and reliable amplification refractory mutation system (ARMS) technique for sex determination of red panda based on the exon 4 of the ZFX/ZFY gene. The amplicons were distinguished simply by agarose gel electrophoresis, exhibiting one fragment in females (X: 300 bp) and two in males (X: 300 bp, Y: 166 bp). Robustness of this ARMS system was confirmed by testing both 43 captive red pandas using DNA samples with known-sex and 10 wild red pandas using faecal DNA samples with unknown sex. |
