遗传作用

We presumed that the term of Y-linked inheritance cannot confuse with that of sex-limited inheritance, and that though the sex-limited factor and the sex-influenced inheritance gene are both located on autosome with some distance, but they are still different.

对现行的遗传学教材中存在的专业术语同名异义现象进行探研，针对Y连锁遗传、限性遗传、从性遗传、单倍体、多倍性和累加作用等专业术语存在的表达不清，相互矛盾，同名异义等问题，进行分析探讨，并提出Y连锁遗传不能与限性遗传相混淆，限性遗传和从性遗传的基因是位于常染色体上，但二者存在区别。

The SCA effect was important in the heterosis of the spike number per plant of the intervarietal hybrid, the SCA and GCA were both important in the heterosis of the grain number of main spike of the intervarietal hybrid; the SCA effect played an major role in the heterosis of the spike number per plant of the interspecific crosses of the common wheat and club wheat, the SCA effect played an major role in the heterosis of the 1000-grain weight of the interspecific crosses of the common wheat and spelt wheat.

普通小麦品种间杂种每株穗数杂种优势中，特殊配合力所代表的非加性遗传效应起了主要作用，而主穗粒数杂种优势中一般配合力、特殊配合力所代表的加性、非加性遗传效应所起的作用相当；普通小麦与密穗小麦种间杂种主穗粒数杂种优势中特殊配合力所代表的非加性遗传效应起了主要作用；普通小麦与斯卑尔脱小麦间杂种千粒重杂种优势中特殊配合力所代表的非加性遗传效应起了主要作用。

The result suggested that different genomes had different genetic speed or stability during evolution.3 The similarities co-efficiency between wild emmer and hexaploid synthetic was higher than that between wild emmer and common wheat. So that crossing among species is not a simple combination of genomes, but involve introgression of chromosomes, and the evolution made by this action was bigger than that made by environment.4 According to the results of salt tolerance identification, the salt tolerance of wild emmer is lower than that of common wheat in the whole.

野生二粒小麦与普通小麦之间的遗传相似系数稍高于野生二粒小麦与其与节节麦合成的双二倍体的遗传相似系数，说明物种之间的杂交并不仅仅是染色体组简单的合并，其中包括复杂的染色体组本身的一些特性以及染色体之间的互渗且这种作用远大于环境作用所引起的变化。

By using wheat with recessive ph gene as parents in wide crosses, new wheat lines with alien chromosome segments, such as TKL1, were obtained. Gene phKL and its combinant have new usefulness for studying on genetic mechanism of homoeologous chromosome pairing and alien gene transfer.

phKL基因及其重组体在染色体配对的遗传作用机制和外源基因转移方面存在新的应用价值。

Aimed at the study of Lauraceae system classification in domestic and overseas,genetic diversity and genetic variation between Cinnamomun micranthum Hayata natural populations and Ex-situ conservation poputations and relationship among Its Close Relative Species of Cinnamomum camphora Presl,Cinnamomum burmannii(C.G.etTh.Nee) Bl,Phoebe bournei Yang. Litsea subcoriacea Yang et P.H.Huan. Neolitsea aurata Koidz,Lindera communis Hemsl and Persea Americana Mill.were studied by inter-simple sequence repeats molecular marker.The research aimed at genetic variation between Cinnamomun micranthum Hayata populations,so that can offer the molecular theoretic and practical method for conservation and utilization of Cinnamomun micranthum Hayata populations.

针对目前国内外对樟科植物系统分类的研究现状，本研究采用ISSR分子标记技术对樟科沉水樟天然居群和迁地保护居群的遗传多样性进行研究，从分子水平上分析沉水樟种群的生态遗传及其遗传变异规律；同时利用ISSR分子标记技术比较沉水樟及其近缘种香樟、阴香、闽楠、桂北木姜子、新木姜子、香叶树、鳄梨在分子水平上的亲缘关系，揭示这些树种在樟科植物系统进化中的作用与地位，探讨沉水樟及其近缘种的遗传多样性及其分化格局，为樟科植物的系统分类提供分子水平的依据。

Local scientists believe that when GM corn cross-pollinates with traditional varieties, some genetic effect disturbs the offspring.

当地科学家相信，转基因玉米一旦与传统品种发生异花授粉，某些遗传作用就扰乱它们的后代。

The aim of this article is to review the main perspectives of psychiatric genetic epidemiology and to provide several illustrative examples for readers of various genetic diatheses as they relate to cognitive function, personality characteristics, as well as to the interaction of genetic and environmental factors.

本文旨在对於精神遗传流行病学几个观点作一介绍，并藉由一些研究的结果举例说明，让读者对於精神疾病的遗传基因、认知功能、人格特质等各种遗传机制有不同的认识，并进一步了解遗传与环境之间的交互作用。

Path analysis of nine traits, which were highly correlated with tree volume, showed that the direct contribution of DBH and height on the variations of tree volume took up about 63% of the total variations. On the other hand, those traits, such as tree crown and wall/lumina, affected the volume strongly by indirect way of the genetic correlation with DBH and height.

通过对与材积性状紧密相关的胸径等9个性状的通径分析发现，胸径和树高两个性状对单木材积的直接作用占材积总变异的63％，其余性状的直接控制作用很小；冠幅、壁腔比等性状通过胸径对单木材积具有很大的间接遗传控制作用，这种控制是通过与胸径、树高的遗传相关实现的。

Decades of extensive efforts have been dedicated to the searching of DNA sequence variations that increase the risk. However, the non-Mendelian complex mode of transmission made genetic studies in Schizophrenia quite difficult.

大量的双生子、寄养子和家系研究的数据表明在精神分裂症的发病过程中遗传因素有很重要的作用，多年来为了寻找提高精神分裂症风险的DNA序列上的突变已付出了巨大的努力，然而该病的遗传方式非常复杂，并不符合简单的孟德尔遗传规律，使得遗传分析至今还没有获得令人满意的结果。

Based on the framework of the Alife evolutionary model, we proposed two different models according to Lamarck direct evolution and Baldwin effect. They are called genetic controlled evolutionary reinforced model and autonomous genetic reinforced model, both of which embodied in the mutual effect of learning and evolution.

在基于遗传算法的人工生命进化模型的结构框架下，分别依据Lamarck直接遗传方式和Baldwin效应间接遗传方式两种不同的遗传行为方式，设计了遗传监视进化强化模型和自律遗传强化模型两种不同风格的进化模型，它们都有效地体现了学习和进化之间的双向作用关系。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
