Abstract
The Chinese sika deer (Cervus nippon) is a rare and vulnerable animal in China for medical use. In this study, the genetic diversity and population genetic structure of 113 Chinese sika deer from 4 populations (Linyi Farm, LF; Linyi Park, LP, Yangzhou Farm, YF; Yangzhou Zoo, YZ) were investigated with 14 microsatellite loci. Eighty-three alleles were detected at the 14 loci in all populations. The expected heterozygosity ranged from 0.257 to 0.863 and the observed heterozygosity from 0.226 to 0.821. The polymorphism information content at different loci ranged from 0.217 to 0.825. The results of the HWE (Hardy–Weinberg equilibrium) tests indicated that only four loci (CEH-5, BL42, Mber70, and CEH-2) were in HWE (P > 0.01). The mean number of alleles per population ranged from 3.21 to 5.64, observed and expected heterozygosities ranged from 0.568 to 0.685, respectively. Positive inbreeding coefficient (FIS) values were found in every population. FST values ranged from 0.101 in the LF to 0.155 in the YZ. The genetic identity ranged from 0.1236 to 0.1645. The genetic distance ranged from 0.4746 to 0.6025. The results of this study indicate moderate genetic variation and polymorphism across the loci. Appropriate breeding strategies should be designed for deer in captivity.
