The results of POPGENE analyze indicated that it was moderate level of the genetic diversity of Dipelta, mean PPB (percentage of polymorphic bands) h and I of 4 species of Dipelta as below: D.wenxianensis.(PPB=62.02%,h=0.1850,I=0.2826); D.yunnanensis (PPB=40.31%, h=0.1238, I=0.1874); D. floribunda (PPB=36.82%, h=0.1395,I=0.2045); D. elegans (PPB=15.51%, h=0.0583,I=0.0861). Genetic diversity in D.elegans is the lowest. It is possibly caused by the endemic distribution and local ecotope.

POPGENE分析结果表明，文县双盾木的多态位点百分率平均为62.02%，Nei&s基因多样性指数平均为0.1850，Shannon&s信息指数平均为0.2826；云南双盾木的PPB平均为40.31%；h值平均为0.1238；I值平均为0.1874；双盾木两个居群的PPB平均为36.82%；h值平均为0.1395；I值平均为0.2045；优美双盾木两个居群的PPB平均为15.51%，h值平均为0.0583；I值平均为0.0861；因此，我们认为双盾木属4个种的遗传多样性适中；而优美双盾木由于分布上的地理限制，居群的生境比较孤立，其遗传多样性较低。

Since genetic relationship between green foxtail from different region and foxtail millet resisted to herbicide is different, foxtail millet, which is relatively far away from green foxtail in local region as for genetic relationship, resist to herbicide is popularized in order to decrease the ecology risks.

由于不同地区的青狗尾草和抗除草剂谷子亲缘关系不同，可以推广与当地青狗尾草亲缘关系较远的抗除草剂谷子以减少抗除草剂谷子种植后的生态负效应。

Characters of genetic diversity are followed Three allozyme loci AAT-3, PGD-1 and PGD-2 are monomorphic. The IDH-1 was silence in S.glauca but it was active in S. itlica and S. virids. Genetic diversity of green foxtail was more than that of most of other annual primary self-pollinated plant. The yellow foxtail was complex.

我国北方青狗尾草遗传多样性特征是：AAT-3、PGD在所有供试种源中均表现单态，金狗尾草与青狗尾草和谷子相比，IDH—1表现沉默，青狗尾草同其它一年生以自花授粉为主的植物相比表现更高的遗传变异性，金狗尾草表现为倍性复合体。

In other words,163 sites in crested ibis genome were detected.The bands from 23 primers showed polymorphism.Minimurn of polymorphic ratio was 0,maximum was 85.71%,and average was 48.99%.In the population which was composed by 37 individuals, most of genetic distances between two arbitrary individuals were less than 0.1.The results showed that the degree of similarity among crested ibises was high while genetic diversity in thepopulation was low accordingly.

我们在对Operon公司OPG系列和OPA系列引物进行优化筛选的基础上，用24条随机引物共扩增出163条谱带，即检测了朱鹮基因组中的163个位点，其中23条引物的扩增结果具有多态性；谱带的多态比率最小为0，最大为85.71％，平均为48.99％；在由37只朱鹮组成的种群中，任意两个个体之间的遗传距离绝大多数在0.1以下。

The amount of DNA was enough to apply t o genetic analysis by RAPD. Eighteen primers had stable effect. The genetic dist ances are between 30.52%and 10.18%,which showed that the relationship between 16 crested ibises was similar.

获得的DNA可进行RAPD研究分析，1 8条引物扩增结果稳定，遗传距离指数介于30.52%～10.18%之间；揭示16只朱间亲缘关系较近。

The wide application and rapid development in genetic engineering open up a broader path for plant genetic improv...

基因工程的迅速发展和广泛应用为植物的遗传改良开拓了广阔的前景。

One hand Insurers expect to collect the Genetic Information of Insurant as much as possible, the other hand, Insurants want to uphold their Genetic Privacy, result as the conflict of interests.

保险人一方希望尽可能的收集被保险人的基因信息，而被保险人希望尽可能的维护自己的基因隐私，这就引发了两者的利益冲突。

The taxon relationshops based on Nei's genetic identity and genetic distance were consistent with results obtained from karyotypic analyses.

Nei的遗传距离和遗传一致度进行的聚类分析基本符合传统形态学、细胞学等研究结果：即同属于斑腿蝗科的中华稻蝗和长翅素木蝗遗传距离最小( D = 0.559)，遗传一致度最高( I =0.576)。
