查询词典 polymorphism

Polymorphism was detected for exon 3 of BMP4 gene in four sheep breeds. For exon 3, three genotypes were detected in four sheep breeds. In Small Tail Han, Chinese Merino, Corriedale and South African Mutton Merino sheep, frequency of genotype AA was 0.017, 0.216, 0.115, 0.429, frequency of genotype AB was 0.102, 0.317, 0.269, 0.500, frequency of genotype BB was 0.881, 0.467, 0.616, 0.071, respectively. Sequencing revealed one singlenucleotide mutation C→A at 305 bp of exon 3 of BMP4 gene in genotype BB in comparison to genotype AA, and this mutation resulted in an amino acid change of alanine→aspartic acid.

对于外显子3的引物，在4个绵羊品种中都检测到3种基因型；统计结果表明：小尾寒羊、中国美利奴绵羊、考力代绵羊、南非肉用美利奴绵羊AA基因型频率分别为0.017、0.216、0.115、0.429，AB基因型频率分别为0.102、0.317、0.269、0.500，BB基因型频率分别为0.881、0.467、0.616、0.071；测序结果表明：BB型和AA型相比在BMP4基因外显子3第305位碱基处发生C→A的突变，该突变导致氨基酸由丙氨酸改变为天冬氨酸；BB型小尾寒羊平均产羔数分别比AB型和AA型多0.61只（P.05）和1.01只（P.05）。

By using the Neighbor-joining method, a dendrogram was obtained based on genetic distances. The bootstrap values were evaluated for each crunode of the dendrogram by means of bootstrap test. The results showed that the mean heterozygosity of the whole native egg-typing duck breeds population was lower than those of native chicken breeds and goose breeds, suggesting that the genetic diversity in those duck breeds population is relativly rare and should be strengthened. The rank of the heterozygosity was consistent with that of the polymorphism information content. The results of the genetic distances between them indicated that the differentiation occurred long time ago. In the dendrogram, Weishan pocked, Youxian pocked, Huainan pocked, Guangxi pocked and Jingjiang pocked were classified into one goup, Chaohuand Enshi pocked were the second group, Liancheng white, Putian black, Jinding, Shanma, Sansui and Shaoxing were the flnra grong.

结果表明：我国所有蛋鸭品种全部群体的平均杂合度较低，其遗传多样性相对贫乏，各保种场要加强多样性的保护；各品种的平均多态信息含量的高低与群体平均杂合度的顺序完全一致；遗传距离的计算说明了13个品种的遗传距离较远，分化时间较长；13个地方蛋鸭品种被聚类为3个类，微山麻鸭、攸县麻鸭、淮南麻鸭、广西小麻鸭、荆江麻鸭聚为一类；巢湖鸭和恩施麻鸭聚为一类；福建省的鸭种连城白鸭、莆田黑鸭、金定鸭、山麻鸭与三穗鸭、绍兴鸭聚为一类。

(1) Exon 6,7,8 have no relation with the susceptibility of HCV infection. The genetic basis of the four amino acids is highly conserved in Chinese population. Because other sites of CD81 protein are highly conserved among species, there is no or very rare polymorphism of CD8I in Chinese people.(2) The susceptibility of HCV infection has nothing to do with the genetic basis of the ligand binding region of LDLR.Postgraduate DongQiumingDirected by Professor Gao Jinsheng Professor Lu Daru

（1）CD81外显子6、7、8与HCV感染的易感性无关，以上四个氨基酸的遗传基础在中国人中是高度保守的；由于CD81蛋白的其它位点在种间是高度保守的， CD81，LDLR单核菩酸多态拄与丙型肝炎病毒感染易感性的相关性研究摘要因此，在中国人群中 CDSI蛋白的多态性稀少或不存在。u）HCV感染的易感性与LDLR的配体结合结构域的遗传基础无关。
