Genetic diversities of the giant panda (Ailuropoda melanoleuca) in Wanglang and Baoxing Nature Reserves

Genetic variations in the giant panda populations in Wanglang and Baoxing Nature Reserves were evaluated in this study. Panda feces were collected from these two reserves and DNA samples extracted from the feces were genotyped at 13 microsatellite loci. A total of 130 alleles were identified from the 13 microsatellite loci in 63 giant pandas, including 35 private alleles in Wanglang, 53 private alleles in Baoxing, and 42 alleles shared between the two populations. The mean observed heterozygosity, average number of alleles, average number of allelic richness, and average polymorphism information content were 0.488, 6.2, 3.302, and 0.612, respectively for the Wanglang population and 0.553, 7.6, 4.050, and 0.747 for the Baoxing population. A moderate degree of genetic differentiation (F st = 0.26) and no gene flow were found between these two populations.
