(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。

In the progress of tumor development, it shows heterology, and formed different subgroup, promote metastasis.

其表现为肿瘤在组织形态学、核型，免疫表型，遗传标志物，生长率，细胞产物，药物敏感性以及其他细胞组织学特征方面呈现广泛的多态性，从而产生不同转移能力的癌细胞。

Johannsen experimented with the Princess bean and found that if the self-fertillzing parent plants were from a mixed population, then selection did indeed work. He described the offspring of single parent as a ' pure line ' and stated that they were genetically identical. In 1905 he coined the terms ' phenotype ' to describe the outward appearance of an individual and ' genotype ' to describe the genetic makeup of an individual.

约翰逊用菜豆做实验，结果发现：如果自体受精的亲本植株来自一个混合群体，那么选择确实是有效的，而被称为"纯系"的单亲后代则表明它们在遗传上是一致的。1905年他首次采用"表现型"来描述某一个体的外观形状，用"基因型"来描述某一个体的遗传组成。

The results showed that exon 1 had the genotypes of AA, BB and CC, while intron 1 had the genotypes of DD, EE, FF and GG. There existed gene polymorphism in inter-species but not in intra-species. All the test species displayed genetic monomorphism and 100% of purity.

结果表明：外显子1有AA、BB和CC3种基因型，内含子1有DD、EE、FF和GG4种基因型；种间存在基因多态性，种内没有多态性，所有种均表现出遗传的单态性和100%的纯合度。

The major gene heritability and polygene heritability were 64.17% and 14.76% respectively, which showed major genes played major role in seed setting rate.

在主基因作用的效应中，加性效应和显性效应各占主基因效应的50％；主基因的遗传率较高，分别为56.97％和44.26％；多基因的遗传率很低，分别为1.24％和3.05％；环境对结实率的影响显著，其方差占总表型方差的43.07％和52.99％。

Apparently, the giant panda's evolution from Ursus to Ailuropoda required the change of only a few genetic messages (5 or 6 perhaps), yet the phenotypic and lifestyle change from a standard bear is considerable. The transition could therefore be effected relatively swiftly.

显然，从熊到大熊猫的进化只需要少数遗传信息（也许5或6个遗传信息）的改变；然而，在表型和生活方式上与一头标准熊相比，发生了相当大的改变；而且这种转变过渡可能是相对迅速地达到的。

In the present study, full-length rDNA sequences from the domestic and wild type of Chinese oak silkworm, Antheraea pernyi (GenBank No. GU073314 and GU073315, respectively) were obtained and comparatively analyzed on their genetic variation.

测定了放养型和野生型柞蚕的rDNA ITS-2全长序列（GenBank登录号：GU073314、GU073315），并分析了二者之间的遗传差异。

Japonicus used in this experimentation is matemal inheritance.5 Sequence analysis of mitochondrial 16S rRNA and COI gene and molecular phylogeny of four species of sea cucumber500 bp 16S rRNA and 540 bp COI fragment were obtained by PCR method from mitochondrial DNA of four species of sea cucumber, Apostichopus japonicus, Holothuria fuscogilva, Cucumaria frondosa and Mensamaria intercedens. Variable sites, nucleotide diversity, average number of nucleotide differences and average number of nucleotide substitutions per site were calculated to analyze sequence difference, and phylogenetic trees were constructed by the NJ and ME method.

结果显示在来自这5组家系的100个后代中仅检测到母本的单倍型，刺参的线粒体遗传模式表现为典型的母系遗传。5 4种海参16S rRNA和COI基因片段序列比较及系统学研究采用PCR技术对山东荣成、长岛、俄罗斯和日本的刺参，黄乳海参，北大西洋瓜参，二色桌片参的16S rRNA和COI基因片段进行了扩增和测序，分别得到了长度约为500 bp和540 bp的片段。

BACKGROUND: Retinitis pigmentosa is a group of commonest genetic blindness-inducing eyeground diseases, which have relative great heterogenicity in both heredity and phenotype. Pierce et al discovered a new retinal photoreceptor cell specific gene-RP1 in 1999, and also found in their following research that the mutation of this gene can induce autosomal dominant RP .

背景：视网膜色素变性(retinitis pigmentosa，RP)是一组最常见的遗传性致盲眼底病，在遗传和表型上均具有较大的异质性。1999年Pierce等发现了一个新的视网膜感光细胞特异基因--RP1，之后的研究发现该基因的突变可导致常染色体显性遗传RP(autosomal dominant RP，adRP)。

This paper pointed out that the essential of geoherbs is continuers quantities variation at population level, geoherb's populations are different in gene frequency with the others'; geohersm are quantitative trait loci controlled by multi-gene or combination with multiple-gene and major gene at individual level.

指出道地性的遗传本质在居群水平通常是个量变的过程，它与种内其他非道地药材区别主要表现为居群内基因型频率的改变；在个体水平表现为微效多基因控制的数量遗传，或是微效多基因和主基因联合控制的数量性状。
