Eighteen novel polymorphic microsatellite loci developed from the Père David’s deer ( Elaphurus davidianus )

Père David’s deer is a severely bottlenecked species but without showing inbreeding depression, making it essential to develop molecular markers to explore her genetic mechanism of population recovery. In this study, we isolated 18 novel polymorphic microsatellite loci from a dinucleotide-enriched library. This suit of markers presented 2–3 alleles for each locus and their observed and expected heterozygosities were 0.057–0.610 and 0.056–0.598, respectively. These new microsatellite loci had an average of 2.12 alleles and thus contributed to relatively low exclusion probabilities of parentage and paternity testing (0.768 and 0.921). However, when these loci were examined in combination with previous microsatellite markers, overall probabilities of parentage and paternity exclusion went up to 0.905 and 0.990, respectively, showing that these 26 microsatellite loci should be adopted together in future genetic analyses for this highly inbred species.
