摘要
Horizontal starch gel electrophoresis was used to investigate the genetic structure of six populations of Ruditapes philippinarum in the coast of China. Seven enzymes revealed eleven putative loci, and seven of them were polymorphic, PGM^＊, MDH-1^ ＊, MDH-3^＊, LAP-1^＊, LAP-2^＊, MPI-1^＊ and MPI-2^＊. The proportions of polymorphic loci of R. philippinarum populations varied from 0.454 5 to 0.636 4. The values of observed and expected heterozygosities were from 0.039 4 to 0.154 5 and from 0.111 1 to 0.238 5, respectively. Nei＇s genetic distance varied from 0.003 3 to 0.025 3 with an average of 0.013 5. It is suggested that the genetic diversity of R. philippinarum was high.
水平淀粉胶化电气泳动被用来在中国的海岸调查 Ruditapes philippinarum 的六张人口的基因结构。七酶揭示了十一通常认为的 loci，并且他们中的七个是多态的， PGM~* ， MDH-1~* ， MDH-3~* ， LAP-1~* ， LAP-2~* ， MPI-1~* 并且 MPI-2~* 。R 的多态的 loci 的比例。philippinarum 人口变化了从 0.454 5 ～ 0.636 4。观察并且期望的杂合现象的价值从 0.0394 ～ 0.154 5 并且从 0.1111 ～ 0.238 5 分别地。Nei “基因距离从 0.003 3to 改变了的 s 0.025 3 与一般水准 0.013 5。R.philippinarum 的基因差异高，这被建议。
