采用RAPD分子标记技术,分析了大连地区渤海沿海6个菲律宾蛤仔种群的遗传多样性及其分布。12个随机引物共扩增出104个位点,其中92个为多态位点。研究结果表明:大连渤海沿海的菲律宾蛤仔种群具有较高的遗传多样性,种群之间存在着一定数量的遗传变异。
Using RAPD markers, the genetic diversity and distribution of six Ruditapes Lutjanus populations in coastal area of Bohai Sea in Dalian were analyzed. Twelve random primers amplified a total of 104 loci, of which 92 were polymorphic loci. The results showed that: Ruditapes philippinarum population along the Bohai Sea coast in Dalian has a high genetic diversity, there are a certain number of genetic variation among populations.
