우리나라 피조개 집단의 유전적 다양성을 분석하기 위해 남해안 5개 지역의 피조개 443마리를 수집하여 6개의 다형성이 높은 microsatellite 마커를 이용하여 분석하였다. 5개 집단의 유전자좌당 대립유전자는 10-28개의 범위였으며, 각 지역별 microsatellite 마커의 평균 대립유전자 수는 JHH (진해 양식집단) 이 15.5로 가장 적었고, GJ (강진 자연집단) 이 20.3으로 가장 많았다. 평균 기대 이형접합률은 SR (사량자연집단) 이 0.817로 가장 낮았고, GJ (강진자연집단)이 0.831로 가장 높았으며 JHH (진해양식집단) 은 0.822로 자연집단에 비교해 의미적인 차이는 없었다. 집단 간
The genetic variation of Ark Shell, Scapharca broughtonii black was estimated using six polymorphic microsatellite (MS) loci in 443 individuals collected from five populations in Korea. The mean numbers of alleles per locus in five populations were 10-28. The mean number of alleles per locus in Jinhae Hatchery (JHH) population showed the least value as 15.5, but that in Gangjin (GJ) population showed the most value as 20.3. The mean expected heterozygosity in Saryangdo (SR) population showed the least value as 0.817, but that in Gangjin (GJ) population showed the most value as 0.831. In Jinhae hatchery(JHH) population, the mean expected heterozygosity was 0.822, there was no significant difference from those of wild population. The
