한국산 부산입술대고둥(Euphaedusa fusaniana)의 아이소자임 변이
황보학,이준상,조등현 江原大學校 附設 環境硏究所 1994 環境硏究 Vol.11 No.-
Electrophoretic variations in isozymes encoded by 16 loci were studied to estimate genetic variation and to assess phyletic relationships, and biogeographic pattern of distribution of the Euphaedusa fusaniana collected from Sehwa, Aeweol, Samchuck, Tongdosa, Gernundo, and Y?su areas in Korea was discussed with respect to the isozyme variation. The 180 apecimens were examined. Means of allele per locus(?) and polymorphism(?) were 1.528 and 45.5%, respectively and hetrozygosity (?_(D)) was 0.205. Samchuck population showed lower mean value of allele per locus(?=1.46). Higher polymorphism(P=57.14%) was observed among Tongdosa popualtion. Aeweol population showed slightly lower genetic variation (H_(D)=0.15) than others. Average genetic similarities(?) among the six populations was 0.716 Aeweol and Samchuck populations were genetically closer(S=0.903) than others. However the S value between Y?su and Samchuch populations was low(S=0.562). Average genetic distance(?) among the 6populations were 0.267. Both Aeweol and Samchuck populations have closer genetic distance (D=0.067). Genetic distance pattern was similar to genetic similarity pattern.
