본 연구는 산양 7 품종을 대상으로 (Saanen (88), Laoshan (67), Toggenburg (32), Alpine (12), Anglonubian (9), Jamnapari (7), Black Bengal (4)) 13종의 초위성체 마커 (microsatellitemarker)를 활용하여 유전적 다형성 분석을 실시하였다. 대립유전자 수는 4개 (INRA005) 부터 18개 (SRCRSP23)까지 확인되었으며, 관측이형접합율 ($H_{obs}$)과 기대이형접합율 ($H_{\exp}$) 그리고 다형성 정보지수 (PIC) 값은 각각 0.482 ~ 0.786, 0.476 ~ 0.923 그리고 0.392 ~ 0.915로 나타났다. 품종별 유전적 거리를 확인하기 위하여 실시한 주성분분석 (PCoA) 결과는 요인대응분석 (FCA) 분석과 유사한 결과를 보였으며, 동일개체출현빈도는 $2.47{\times}10^{-15}$으로 확인되었다. 따라서 본 연구 결과는 산양 품종 개량 및 보존에 있어 기초자료로써 유용한 자료로 활용 가능 할 것으로 사료된다.

In this study, genotyping was executed by using 13 microsatellite markers for genetic diversity of 224 Gorals (Saanen(88), Laoshan(67), Toggenburg(32), Alpine(12), Anglonubian(9), Jamnapari(7) and Black Bengal(4)). The number of alleles was observed 4 (INRA005) to 18 (SRCRSP23) each markers. Observe...
In this study, genotyping was executed by using 13 microsatellite markers for genetic diversity of 224 Gorals (Saanen(88), Laoshan(67), Toggenburg(32), Alpine(12), Anglonubian(9), Jamnapari(7) and Black Bengal(4)). The number of alleles was observed 4 (INRA005) to 18 (SRCRSP23) each markers. Observed heterozygostiy ($H_{obs}$), expected heterozygosity ($H_{\exp}$) and polymorphism information content (PIC) were observed 0.482 to 0.786, 0.476 to 0.923, and 0.392 to 0.915, respectively. Principal Components Analysis(PCoA) results were similar to the results of FCA. NE-I(on-exclusion probability for identity of two unrelated individuals) was estimated at $2.47{\times}10^{-15}$. In conclusion, this study shows the useful data that be utilized as a basic data of Gorals breeding and development.

그러나 아직까지 산양 품종에 대한 유전적 특성을 파악하는 뚜렷한 연구는 이루어지고 있지 않은 실정이다. 따라서 다양한 산양 품종을 대상으로 생명공학 기술을 활용하여 품종의 유전적 특성 및 다형성 분석을 통해 산양 품종의 유전자원으로써의 가치 제고와 보존 및 육종 개량에 관한 연구 진행이 이루어져야 할 것으로 생각된다.
