| 摘 要： | 采用不连续聚丙烯酰胺凝胶电泳技术研究了中国栉孔扇贝和日本栉孔扇贝两个天然种群的六种同工酶，结果表明：两个种群具有基本相同的基因位点控制同工酶的表达，二者都具有居群内的个体差异，日本栉孔扇贝自然种群的遗传交异明显高于中国栉孔扇贝自然种群，说明环境对栉孔扇贝种内种群的基因表达很大的影响。

| Abstract: | The analysis of two populations of scallop,Chlamys farreri from China and Japan has been carried out using 6 isozymes to determine the genetic variation by polyacrytamide gel electrophoresis(PAGE).The results show that the genetic diversity of Japan population is higher than that of China population with 45.45% of the proportion of polymorphic locus (P.99),0.1295 of the mean observed heterozygosity(Ho),0.1695 of the mean respected heterozygosity(He).In China population,these values are 41.18%,0.1531,0.2331 accordingly.In general,the hybridizition technique between subspecies for improvement of quantitative and qualitative traits is practicable. |
