优势基因

Using Pseudomonas syringae and Pantoea ananas , the dominant ice nucleation active bacteria strains from Yunnan province, as receptors of genetic engineering recombination, and Escherichia coli S17/pZJ25∶∶Tn5 as donator. By transposon Tn5 induced mutants method, the Tn5 was inserted and integrated into the genome of wild type INA + bacteria. INA + mutant as INA - when the linear continuous of INA + gene destroyed.

以云南省冰核细菌的优势种类丁香假单胞菌Pseudomonassyringae和菠萝泛菌Pantoeaananas为重组基因工程菌的受体菌，采用Tn5转座子诱变技术，以大肠杆菌EscherichiacoliS17/pZJ2 5∶∶Tn5作为转座子诱变的供体菌，使Tn5插入并整合到冰核细菌基因组中，使冰核基因的线性连续性被破坏，失去冰核活性。

The results showed that the hereditary mode of handedness or preferential foot or hand-clasping is the dominant heredity of single gene of autosome,and the right type of all of them is the dominant character.

采用Slater区分单基因和多基因遗传的计算模式及Smith无偏分析方法对21个家系资料的分析表明：利手、优势足、扣手特征均为常染色体单基因显性遗传，R型为显性性状。

However, they all boil down to the idea that the relatives of those who are gay gain some advantage that allows genes predisposing people to homosexual behaviour to be passed on collaterally.

然而他们都归结为这样的想法，即同性恋的亲属们有一些优势，这些优势使偏好同性恋行为的基因可以附带传递下去。

In study of equational data on bipolar disorders, the application of linkage analysis was limited, but the results of else three statistical models were similar. They all suggested that the relation between DRD2P or COMT and bipolar disorders had no significance.

在平衡数据的双相情感性精神障碍家系资料致病基因位点的研究中，连锁分析的应用受到限制，而其它三种统计模型的结果一致，DRD2P和COMT基因位点与疾病的关系均无统计学意义，但随着样本含量的增大，广义估计方程表现了一定的优势。

The other idea, since there is evidence that male homosexuals, at least, are more likely than average to come from large families, is that the genes for gayness bring reproductive advantage to those who have them but are not actually gay themselves.

其他的想法，由于有证据表明，至少男同志比一般人更有可能来自大家庭，这是否是同性恋基因给那些有同志基因但实际上并不是同志的人带来的生殖优势呢？

This can be the case for genes with a heterozygote advantage, such as sickle cell anemia or Tay-Sachs disease, which in their heterozygote form may offer an advantage against, respectively, malaria and tuberculosis.

有杂合体优势的基因就是这种情况，如镰状细胞贫血或泰-萨克氏症在其杂合子形式可以分别提供抵御疟疾和肺结核的优势。

This course systematically describes the structure and function, transmission, expression and regulation, and evolution of genetic materials, covering basis of cytology for inheritance, molecular basis of genetic materials, Mendel's principles of inheritance, linkage and sex linkage, genemutation, variations in chromosome structure and number, quantitative genetics, inbreeding and heterosis, inheritance of bacteria and viruses, extranuclear inheritance, gene engineering, genomics, gene expression and regulation, developmental genetics, population genetics and evolution.

本课程全面系统地介绍遗传物质的结构与功能、遗传物质的传递、遗传物质的表达与调控、遗传物质的进化等，包括遗传的细胞学基础、遗传物质的分子基础、孟德尔遗传、连锁遗传和性连锁、基因突变、染色体结构变异、染色体数目变异、数量性状的遗传、近亲繁殖和杂种优势、细菌和病毒的遗传、细胞质遗传、基因工程、基因组学、基因表达的调控、遗传与发育、群体遗传与进化。

In this thesis, we chose two wild rodents inhibiting in the north of China Mongolian gerbil (Meriones unguiculatus and Brandt's vole . The effects of short photoperiod and cold exposure to thermogenesis, and the mechanism of thermogenic regulation were studied. The new genes participating in cold adaptation were also screened by DDRT-PCR.

本文选择了华北地区的两种野生啮齿类（生活在内蒙古荒漠和半荒漠地区的优势鼠种长爪沙鼠和生活在内蒙古干旱草原的优势鼠种布氏田鼠）为研究对象，探讨光照对长爪沙鼠产热的影响，以及在低温因子作用下两种鼠适应性产热变化的机理，并利用差异显示技术试图寻找与冷适应性产热相关的基因。

Cornell plant breeder Steven Tanksley is a co-recipient of the international Wolf Foundation Prize in Agriculture.

他以识别水稻的野生种原的基因的方法对水稻杂种优势（利用这种杂交优势已显著地增加了产量）的理解做出贡献…… Tanksley的研究导致发现这种重要的粮食作物的杂种优势的遗传基础，这是为人类利益而促进农作物培植科学发展的一项意义深远的发现。

The result of bioinformatics analysis showed that it had no remarkable homology with the known genes in GenBank. And the RSG6 gene is localized on the chromosome 8 and 10 of Oryza sativa L. with one copy for each; its homologous fragments exist also on the chromosome 4 and 12 of rice.

精细胞与二细胞花粉的差减文库中获得的在精细胞中优势表达的克隆作为探针，筛选水稻精细胞cDNA文库而得到的基因，它与已知基因没有明显的同源性，为新发现基因。

Do not gum up the work by telling mother what we are going to do .

别告诉母亲我们要干的事，那会把事情搞糟的。

In recent years, application of the partial prestressed concrete beam s is developed.
