遗传效应

Five translocated populations harboured 1,3 or 5 monomorphic loci respectively,while no monomorphic locus in the source population.

It is the main point to focus on the elucidating of the pathogenesis of PNC as a polygenetic inheritance tumor, primarily establishing of the concept of susceptibility gene groups in NPC and the carcinogenesis model of the multi-step Domino effect involved in the molecular mechanisms of NPC dominated by susceptibility gene groups in order to lay out a substantial foundation for finding the high-risk susceptibility factors of NPC, screening the high-risk population of NPC and exploring the targetic and individual measures in diagnosis and treatment of NPC.

现主要阐述鼻咽癌作为一种多基因遗传性肿瘤的病因发病机制，初步建立鼻咽癌易感基因群的概念和鼻咽癌发生发展过程中易感基因群主导的多阶段性多米诺骨牌效应分子机制假说，为寻找鼻咽癌遗传易感风险因子，筛选鼻咽癌高危人群以及探索鼻咽癌靶向性及个体化的诊断和治疗手段奠定实验与理论基础。

The use of the ratio between the migration length and the diameter of the comet head (LDR, see Tice et al., 2000) as a parameter to represent the data of the genotoxic effects in D. polymorpha was found (Bolognesi et al., 2004) to be able to reduce the inter-individual variability of the data (from 20–30% for TL to 5–10% for LDR).

使用的，两者的比例约为迁移长度和直径的彗星头（低剂量辐射，见泰斯对持不同等人， 2000年）作为参数，以代表该数据的遗传毒性效应四多形被发现（ bolognesi等人， 2004年）为了能够减少跨个别变异性数据（从20-30 ％铊，以5-10 ％的LDR ）。

Epigenetic effects,which were defined clearly in recent years,are most often used to denote all those somatically heritable changes in gene expression that do not involve changes in DNA sequence.

后生效应是近几年才定义清楚的一类现象，指所有那些DNA序列没有改变的基因表达后体细胞的遗传表型发生改变的现象。

This study use SOS/Umu test to evaluate the drinking water of various processes for a large waterworks located in north China, both in spring and winter.

本研究应用SOS/Umu生物毒性测试评价了北方某市一自来水厂的A、B、C、D 4套试验工艺在不同的季节各工艺段出水的遗传毒性效应。

The results from the inheritance of resistance to beanfly confirmed that the resistance was controlled by only a major gene and modified by polygenes.

通过三个组合的大豆对豆秆黑潜蝇抗性的遗传分析证实，它由1对主基因控制并有多基因的修饰，确认了不存在次大效应主基因的可能性。

In this study we mapped a grain length controlling gene named Lk-4 with SSR and CAPs markers by screening 800 recessive plants in a BC2F2 population derived from a cross of Shuhui527×Xiaoli and backcrossed with Xiaoli as the donor parent.

对F2和BC2F2 群体籽粒大小形状和千粒重的遗传分析表明，回交能将大部分对目的基因效应具有干扰修饰作用的微效基因多态性除去，从而有利于对目的基因型的准确鉴定；在F2和BC2F2群体中只发现两类籽粒长短表现型，即短粒和长粒，并且二者分离比例符合3：1的典型一对等位基因分离比例。

As a logical implication of the above three points, the raw correlation of kids' SAT scores and family income conflates the true effects of family income with the biological transmission of talent.

以上三点的逻辑结论就是：小孩的 SAT 成绩与家庭收入之间的粗糙的相关性，将家庭收入的真实效应与天分的生物遗传，混在了一起。

Environmental variation in food resources modifies performance of herbivores, in addition to genetic variation and maternal effects.

食物来源的环境变异改变了食草动物的行为，已影响了遗传变异和母体效应。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
