查询词典 polymorphism

AFLP marker technique was used to investigate the genetic relationships between 50 accessions of maize and its wild relatives including teosinte, Tripsacum and Coix With twenty one AFLP primer combinations of PstⅠ/MseⅠ, 641 AFLP amplified bands were obtained, including 586 polymorphic bands with an average of 30 52 per primer combination and the polymorphism percentage of 91 4% Cluster analysis using UPGMA method based on the data of AFLP showed that the 50 materials could be divided into...

用AFLP分子标记技术对 5 0个有代表性的玉米及其野生近缘种大刍草、摩擦禾、薏苡材料进行了遗传关系分析。利用 2 1个PstⅠ MseⅠ引物组合检出可辨认带共 6 4 1条，其中多态性带 5 86条，平均每对引物得到 30 5 2条多态性带，多态性 91 4 %。聚类分析结果表明，可以将 5 0个材料分为 3大类，与已有的玉米族分类一致，但与玉蜀黍属内的种间和种内分类存在差异，说明大刍草各种内存在较大的遗传多样性。本实验发现玉蜀黍属与摩擦禾关系比与薏苡的关系更近，但并没有发现玉米与小颖玉米亚种比与其他大刍草的遗传关系更近。

Polymorphism in diploid species G.arboreum was the same as in tetraploid species G.hirsutum,both were 11.84%.

Results A novel polymorphism in the ABCA gene was found in two patients:M V which exists in exon7 of ABCA gene and it's cDNA location is A09G and converses amino acid from Me thionine to Valeric.

果M V是一个新发现的ABCA基因SNP，此位点在外显子7，cDNA位置为A09G，并导致位氨基酸由甲硫氨酸转变为缬氨酸。

Genetic diversity among 7 populations of Trillium tschonoskii were analyzed by using inter SSR and amplified fragment length polymorphism molecular markers. The results were as follows:(1)ISSR: 12 out of the 100 primers showed consistent banding patterns and amplification, a total of 135 bands were produced with an arrange of 250-2500bp, 46 of which (34.07%) were polymorphic.

应用锚定SSR和限制性片段多态对7个延龄草居群的遗传多样性进行了分析，结果如下：从100个引物中筛选出12个ISSR引物，在250-2500bp之间共扩增出的135个条带，其中多态性带为46，占34.07％。

We analyzed the pattern, heredity rule and possible mechanisms of karyotype polymorphism in the species of the tufted deer.

根据核型图、C-带及薄层扫描结果分析了毛冠鹿种内染色体多态的表现形式、遗传规律及可能的产生机制。

Therefore, cloning of TYR gene could be useful for further study on polymorphism and correlation on duck feather color.

Methods The polymorphism at nucleotide 307 in the 4th exon of HCR gene was detected in 118 patients of the Uigur population with psoriasis vulgaris and in 127 normal controls.

方法测定118例新疆维吾尔族寻常性银屑病及127例正常人对照组的HCR基因第4外显子第307位点基因多态性。

METHODS Genotypes of HCV were determined by restriction fragment length polymorphism analysis of the 5' untranslated regions of different HCVs.

采用限制性长度多态性分析法对采自西安地区的 4 6份和郑州地区的 4 0份 HCVRNA阳性标本进行 HCV基因型分型研究。

Since all objects in the class pool are upcast to their common base class, the polymorphism of the method leads to that which object method will be executed can only be ascertained at runtime.

由于所有位于对象池中的对象都被上溯到它们的基类型，方法多态使得只有在运行时刻才能真正确定到底哪个对象的方法被执行。
