青岛近海魁蚶群体等位基因酶遗传变异研究(英文)

The genetic variation of allozyme in bloody clam from Qingdao coastal waters 

采用淀粉凝胶电泳技术研究了青岛近海魁蚶（Ｓｃａｐｈａｒｃａｂｒｏｕｇｈｔｏｎｉ）自然群体的等位基因酶遗传变异。在１０种等位基因酶中共检测到了２２个基因座位，多态位点比例为４５．５％，位点有效等位基因数分布为１．０００～２．４６９（平均值１．４１５），位点杂合度观察值分布为０．０００～０．５９５（平均杂合度０．１０５±０．０２３），在６个基因座位上存在相当明显的杂合子缺失现象。文中讨论了杂合子缺失的原因。

The samples of bloody clam Scapharca broughtonii were from Qingdao coastal waters. 22 loci in 10enzymes were detected by using starch-gel electrophoresis and the percentage of polymorphic loci was 45.5%. The effective number of alleles per locus varied from 1.000 to 2.469 (mean value 1 415), and the observed heterozygosity per locus ranged from 0.000 to 0.595 (mean value 0 105±0.023). The deficiency of heterozygous individuals obviously existed at 6 loci, and the reasons for it were discussed.
