查询词典 polymorphism

The plum-apricot germplasm resources were analyzed by RAPD markers. The results showed that plum-apricot was more close to the related species with low polymorphism. The clustering results were indicated that most plum-apricots were more close to Chinese plum with the similarity of morphological description, thus the female parent for plum-apricot was probably plum in the occurrence naturally. The result of S allele-specific PCR amplification showed that plum-apricot had only one band with the similarity with plum, thus evolution similarity of plum-apricot was more close to plum than apricot.

5对参试杏梅种质资源的RAPD分析表明，杏梅与其近缘种之间亲缘关系较近，多态性相对较少；聚类分析结果显示大部分的杏梅与中国李的遗传距离较近，与形态学上的描述基本一致，因此杏梅种质资源在自然界中产生时，其母本可能为李；同时S等位基因的扩增结果显示杏梅与李的扩增条数一致，都为一条，因此推断杏梅与李的进化趋同性可能较杏更近。

To detect QTL for the body fat-related carcass traits in beef cattle, the single strand conformation polymorphism assay was used for investigating the K232A substitution in DGAT1. Animals from 4 beef cattle populations (32 Luxi, 28 Jinnan, 32 Qinchuan and 26 Limousin × Luxi cattle) were used to estimate allele frequencies and gene substitution effects on several beef carcass traits.

为研究肉牛与体脂相关的胴体性状的数量性状座位，利用单链构象多态性方法检测了牛DGAT1基因K232A取代的2个等位基因K和A在实验群体中的分布频率，并分析了基因型对4个肉牛群体部分胴体性状的影响。

Dynamic binding 动态绑定 The combination of the last two mechanisms mentioned, redefinition and polymorphism, immediately suggests the next one.

Methods The genotype of 4 SNPs in 108 simple CHD patients and 200 normal people were analyzed by restriction fragment length polymorphism and denaturing high-performance liquid chromatography. The statistical contingency table method was used to analyze SNP genotype frequency and gene frequency in patients and control group;then, the haplotypes were established and their frequencies in the two groups were assessed by PHASE software.
