三态性

Except for variation data, gene descriptions, enzyme information and other biological information for each gene locus are also included. Since RefSeq of NCBI http:∥www:. ncbi. nlm. nih. gov/LocusLink/refseq.

另外，VSD有别于现有的其他变异数据库的主要特点是：一是在基因组、mRNAs和蛋白质三个水平上定位了变异；二是分析了可能影响蛋白质功能的非同义单核苷酸多态性变异(nonsynonymous SNP，nsSNPs)。

Objective To investigate the relationship among 3 GP Ⅱb and the funciton of GP Ⅱb T13959 G in the platelet transfusion refractoriness.

目的：研究血小板膜糖蛋白Ⅱb三种基因多态性之间的关系及CP Ⅱb， T13959 G在血小板输注耐受中的作用。

The swainsonine content changed according to different populations and plants. The swainsonine was not found in the OY2 population of O. glabra var. tenuis,but it was found in OY2 population of O.

ISSR-PCR扩增条带表现了三种棘豆各种群具有丰富的多态性，种群间的差异主要是基因频率不同，在不同种群中也有一些特异位点。

Further work will be required to see if indeed two non-emitting triplet states exist in this region.

进一步的工作将是需要了解两种不发射的三重性态是否确实存在在这一范围。

In the paper the phenotype freguencies of the EAP,ADA and AK1 have been investigated by the emthod of typing of EAP-ADA-AK on the samemixed starch／agarose gel electrophresis among 3 nationalities in Inner Mongolia.(Oroqen,Ewenki and Dawuor.) The distribution of their typy frequencies varied with races.

用同步电泳分型的方法，对中国内蒙古鄂伦春族、鄂温克族、达斡尔族人506份血痕红细胞酶EAP、ADA、AK1遗传多态性进行了研究，被调查群体中均未检出上述三种酶型的变异型。

1Livestock Research Institute, Council of Agriculture(2)Department of Animal Science, National Pingtung University of Science and TechnologyGenetic variation in the N-acetylglucosamine 6-sulfatase (G6S) gene is the key role in caprine Mucopolysaccharidosis IIID.

本研究建立山羊黏多醣症遗传缺陷之单股构型多态性基因型检测方法，应用此方法来检测乙醯醣胺氨基硫酸酶(N-acetylglucosamine 6-sulfatase， G6S)基因型不再需要使用限制酶，可节省检测时间、成本与人力。G6S基因的遗传变异在山羊黏多醣症第三型扮演重要的角色。

The purpose of this paper is to review and analyze recent advances in heterostyly research, with emphases on 1 types, floral syndrome, ancillary polymorphism and population structure of heterotylous species; 2 taxonomy, origin and evolution of angiosperms that exhibit heterostyly; and 3 the evolutionary biology of pollinating characteristics associated with heterostyly.

本文从以下三个方面进行总结和分析：(1)异型花柱植物的类型和花部特征、附属多态性和种群结构；(2)异型花柱植物在被子植物中的分布、起源和演化；(3)异型花柱植物传粉特性和适应意义。

The experiment showed: 1PER, EST and AMY were polymorphic, meanwhile the isozymic chromatograph could identify the cultivars in this study; 2Two multifoliolate cultivars had specific isozyme loci PER-4, and the level of PER activity of the internal cultivars was higher than the external cultivars; 3 Genetic similarity and euclidean coefficient between the cultivars were 0.826-0.952, 0.500-1.118, between the multifoliolate cultivars were 0.904, 0.500; 4 Multifoliolate cultivares were classified for one type, and others for two other types.

结果表明：1测定的5种同工酶中过氧化物酶、酯酶、淀粉酶具有多态性，综合此3种酶酶谱可以鉴定供试的7个品种；22个多叶型品种具有一共同特征酶带PER-4，国内品种的过氧化物酶活性明显高于国外品种；3品种间的遗传一致度为0.826～0.952，欧氏遗传距离为0.500～1.118，多叶型品种间遗传一致度为0.904，欧氏遗传距离为0.500；4等级聚类分析结果为，以欧氏遗传距离0.400为分界，供试品种分为3类，2个多叶型品种为一类，其余的5种三叶型品种分为另两类。

Methods Case control association study was adopted to analyze the association between the 48 bp VNTR polymorphism of DRD4 gene exon III in 510 DSM IV schizophrenics and 171 psychiatrically normal controls.

使用病例对照的关联分析的方法，对符合诊断标准的 5 10名精神分裂症患者/ 171名正常对照就DRD4基因第三外显子 48bpVNTR的多态性进行检测并进行关联分析。

In this study,by PCR amplification with the genomic DNA of three mapping parents,940 SSRs primers were tested for analysis their versatility and polymorphism in melon,cucumber and watermelon.

利用940对SSR引物，对甜瓜、黄瓜和西瓜三套重组自交系群体的作图亲本DNA进行PCR扩增，分析SSR引物在不同瓜类作物间的通用性与多态性。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
