Genetic linkage was tested on 121 segreg ating F2 plants derived from a cross between Avocet S and Yr5 /6 Avocet S.It was showed that the polymorphic DNA fragment S1320 207 was completely linked to Yr5 gene,and S1348 363 closely linked to Yr5 gene.

用121株Avocet S和 Yr5 /6 Avocet S杂交制备的 F2代分离群体进一步进行的遗传连锁性检测表明，多态性DNA片段 S1320 207 和S1348 363 分别与 Yr5 基因完全连锁和紧密连锁。

By conducting broad field investigation, we have found 5 wild populations near the boarder of Yunnan and Sichuan province.

从设计的42对引物中筛选出有效扩增引物28对，其中表明多态性的引物有17对。

And there were great variations in the length of intron in the region of EC8-EC11 in population of cotton bollworm.

在棉铃虫中编码EC8～EC11的DNA序列内含子变异很大，具较高的多态性。

RF showed significant contribution on BUD variation and genotype showed the same contribution on MNed BNC and BUD level but the effects were relatively small compared with that of FA.

利用胞质分裂阻断微核技术分析了叶酸（20、200nmol／L即LF、HF）和核黄素（1、500nmol／L即LR、HR）不同浓度组合以及MTHFR C677T多态性对9d培养的人淋巴细胞基因组稳定性的影响。

Therefore, the major capsid protein could be used as a new genetic tool to differentiate viral genotypes in natural communities.

表明该病毒在自然海域中分布广泛并具有一定的多态性，同时在进化上也存在相当的复杂性。

To consummate the diagnosis system of DMD/BMD, we established the linkage analysis technique to quickly detect carrier and perform prenatal gene diagnosis in the families with DMD/BMD.

结果说明联合采用上述2个多态位点可以对近90％的HA家系作出快速、准确的基因诊断和产前基因诊断 2。

Frequencies of "Caucasoid origin" HLA alleles such as B*08,B*35 and B*50 in Xinjiang Uygurs were higher than other ethnic groups in China.

由于高度多态性，蕴藏丰富的遗传信息，因此，它是人类学和法医学个体识别及亲权鉴定理想的遗传标记系统[2]之一。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
