| 摘 要： | 采用等位酶技术分析了黄海中南部、东海陆架区3个站住的精致真剌水蚤(Euchaeta concinna)的苹果酸脱氢酶(MDH)、苹果酸酶(ME)和山梨醇脱氢酶(SDH)3个酶4个多态住点。生化遗传结构和遗传分化分析表明，3个站住样品的MDH基因型差异明显，不同站住间精致真刺水蚤平均遗传距离(D）为0．0768，平均遗传相似性（I)为0.9259。黄海南部(E3站住)和东海陆架区(E7站位)的精致真刺水蚤之间的D为0.0791；黄海中部(E2站位)与南部(E3站位)之间的D为0.067l。由此推论栖息于黄海和东海的精致真刺水蚤种群之间存在一定程度的遗传分化。

| Abstract: | Using vertical acrylamide gel electrophoresis, 4 polymorphic loci encoded by 3 allozymes of Euchaeta concinna collected from the Yellow Sea and the East China Sea were analyzed. The genetic structure and genetic differentia- tion revealed that the genetypes and phenotypes of MDH were significantly different and that average genetic distance (D) and genetic identity (I) was 0.076 8, 0.925 9 among stations E2, E3 and E7 respectively. The extent of differentiation between E3 and E7 is greater than that of E2 and E7, suggesting hereditary differentiation between E.concinna populations in the Yellow and East China seas. |
