The 30 microsatellite loci are vised in this experiment to analysis the genetic diversity of six sheep breeds in order to offer basis of use and protection of sheep genetics.1 The 30 microsatellite loci which are selected from 41 published ones show polymorphism.

本文利用30个微卫星标记对6个绵羊品种的遗传多样性进行了分析和研究。旨在为绵羊遗传资源的合理利用及保护提供科学依据。 1 从已发表的41个绵羊微卫星位点中筛选出在本实验的6个绵羊品种中表现出多态性的30个位点，共检测到284个等位基因。

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。

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.

方法应用限制性片段长度多态性和变性高效液相色谱法结合测序，分析108例单纯性先天性心脏病患者及200名正常人4个SNP位点基因型；应用列联表法统计分析患者组和对照组各SNP位点基因型及等位基因频率；应用PHASE软件构建单倍型并统计分析患者组及对照组单倍型频率是否存在差异。

Polymorphisms in ESRa gene and association with egg production traits The SSCP detection of 5" flanking regulation region and intronl in ESRa gene showed that two genotypes were detected in 5"flanking regulation region of blue eggshell chicken.

ESRa基因多态性与产蛋性状关系 ESRa基因5侧翼调控区和内含子1区经PCR-SSCP检测，发现绿壳蛋鸡5例翼调控区有两种基因型，两等位基因C的频率为0.86，D的频率为0.14。

Breedings had a relatively smaller number of alleles and genetic diversity than landraces, but no significant differences abserved.

说明不同的连锁群其保守性不同。 3。微核心种质中育成品种与地方品种相比，等位基因数和基因多样性均略低。

Stratified analysis and Logistic regression analysis were performed taken gender, waistline and body mass index as covariants. Results showed that the frequency of the allele and the genotype in variant site was still no associated with the development of T2DM.

以性别、腰围和体质量指数为协变量进行了分层分析和Logisitic回归调整，但结果仍未发现该变异位点各基因型和等位基因与2型糖尿病的发生存在显著性关联。
