The result of genetic analysis conveyed that in partial sequences of mtDNA Cyt b gene there were no variable sites between the eggs and Japanese halfbeak, and the genetic distance between them was 0, however, many variable sites between the eggs and the other fishes of Beloniformes were exised, the variable rate was 18.72-21.3％, and the genetic distance between them were 21.9-26.4％.

遗传学分析结果显示：鱼卵与沙氏下鱵鱼mtDNA Cyt b基因片段序列之间无差异，遗传距离为0，而与其它颌针鱼目鱼类序列间差异达18.72～21.3％，遗传距离在21.9～26.4％之间。

In this study, the genetic structure and genetic diversity of cultured and wild Pacific abalone Haliotis discus hannai were analyzed using AFLP technique on the basis of investigation of the inheritance mode of AFLP markers, and genetic linkage maps of female and male H.

本文通过分析皱纹盘鲍AFLP分子标记的遗传模式，利用AFLP技术对皱纹盘鲍养殖与野生群体进行了遗传多样性及遗传分化研究，并对皱纹盘鲍单对交配的亲本及其F1子代进行AFLP和微卫星作图标记筛选，建立了初步的遗传连锁图谱。

The average percentage of polymorphic bands are 72.06% for ISSR and 66.67% for RAPD respectively. The genetic diversity of ginkgo revealed by ISSR (the average effective number of alleles is 1.8780, the average Nei"s gene diversity is 0.4652, and the average Shannon"s information index is 0.6574) are all higher than those by RAPD (the average effective number of alleles is 1.7842, the average Nei"s gene diversity is 0.4317, and the average Shannon"s information index is 0.6211), while the standard errors of the parameters estimated by ISSR were lower. Therefore, ISSR molecular markers are more suited than RAPD molecular markers when testing the genetic diversity of ginkgo populations and determining the genetic relationship of among populations or among individuals which are much similar hereditarily.

本文应用RAPD和ISSR两种分子标记技术，选取中国5个可能的野生银杏居群共计75个样品，对其遗传多样性进行了研究，得出以下结论：(1)用筛选出的12个RAPD引物和10个ISSR引物进行PCR扩增，分别扩增出65条和68条重复性高、清晰的条带，多态性位点百分率分别66.67%和72.06%，ISSR揭示的银杏遗传多样性(平均有效等位基因数目为1.8780，平均基因多样度为0.4652，平均信息指数为0.6574)高于RAPD所得到的结果(平均有效等位基因数目为1.7842，平均基因多样度为0.4317，平均信息指数为0.6211)，其所估算参数的标准差要低于RAPD所估算出的值，因此，在研究亲缘关系非常近的银杏物种的遗传多样性并试图确定居群间或个体间的遗传关系时，ISSR分子标记技术比RAPD分子标记技术更为合适。
