摘  要:
采集江苏3个不同地域青蛤(Cyclina sinensis)群体样本,运用RAPD分子标记分析群体的遗传结构特征。结果表明,从20条随机引物中筛选出6条引物可用于遗传学分析;启东群体、东台群体和射阳群体的遗传多样性依次递增,且遗传多样性水平相对较高。不同地域群体间遗传分化程度较低,而群体间的遗传距离表现出随地理距离的增加而增大的趋势。

摘  要:
The population samples of Cyclina sinensis in three geographical populations of Jiangsu,were sampled and the genetic structure characteristics of the population was analyzed by using RAPD molecular marker.The results showed that six random primers were selected from twenty primers and were applied on the genetic analysis.The genetic diversity of Qidong population,Dongtai population and Sheyang population arose by their turns.All populations showed a relative high genetic diversity.There were low genetic differentiation degree among different geographical populations and the tendency of the increased geographical distances together with the increased genetic distances.
