Molecular Genetic Diversity of the Gyeongju Donggyeong Dog inKorea

[摘要] References(20)Cited-By(1)The present study wasconducted to analyze the genetic characteristics of the Donggyeong dog and establishparentage conservation systems for it by using 10 microsatellite markers recommended bythe International Society for Animal Genetics (ISAG). A total of 369 dogs from 12 dogbreeds including the Donggyeong dog were genotyped using 10 microsatellite loci. Thenumber of alleles per locus varied from 5 to 10 with a mean value of 7.6 in the Donggyeongdog. The observed heterozygosity and expected heterozygosity ranged from 0.4706 to 0.9020(mean 0.7657) and from 0.4303 to 0.8394 (mean 0.7266), respectively. The total exclusionprobability of 10 microsatellite loci was 0.99955. Of the 10 microsatellite markers, theAHT121, AHTh260 and CXX279 markers had relatively high PIC values (�?0.7). This study foundthat there were specific alleles, 116 allele at AHT121 in the Donggyeong dog when comparedwith other dog breeds. Also, the results showed two (Korean native dogs and the foreigndog breeds) distinct clusters. The closest distance (0.1184) was observed between theDonggyeong dog and Jindo dog, and the longest distance (0.3435) was observed between theDonggyeong dog and Bulgae. The Korean native dog breeds have comparatively near geneticdistances between each other.
