Pedigree Analysis of the Sika Deer (Cervus nippon) using Microsatellite Markers.
The usefulness of microsatellite markers in pedigree analysis of the sika deer (Cervus nippon) was tested in a herd in which the maternal lineages were recorded. Eighteen sets of microsatellite primers originally designed for bovine, ovine, and cervine loci successfully amplified polymorphic DNA in the deer. The numbers of alleles per locus ranged from two to seven, and the observed heterozygosity ranged from 0.350 to 0.900. The resolution power of the markers in paternity testing was then determined by calculating exclusion probabilities and paternity indices. Parentages of the study population were efficiently discriminated by genotyping 17 microsatellite loci. The microsatellite data were also used to calculate the genetic relatedness between individuals, which significantly correlated with coancestry coefficients for the pairs. Our results demonstrate that the microsatellite markers are efficient tools in studying the social structure and behavior of the sika deer, as well as in monitoring the inbreeding status.
