遗传影响

To extrahepatic cholangiocarcinoma and gallbladder carcinoma, the rate of excision is low and the sensitivity to chemotherapy and actinotherapy is poor.

我们的研究表明，胆道癌表遗传的改变能够通过对染色质基因转录的调节来影响癌细胞的增殖进程，而表遗传的改变与蛋白信号的传导密切相关。

Phenotypic plasticity and genetic differentiation are the two major strategies that alien invasive plants can adapt habitat heterogeneity.The polymorphism of invasive plants and the diversity of their dispersal way enable them occupying invaded habitat quickly,and dispersing with a far range.The breeding strategies that agamogenesis and amphigenesis can coexist and trade off according to the habitat and invasive stage can not only promote the invasive population erupted massively,but also directly affect the dispersal mechanism and regulate the genetic structure of the population.

表型可塑性和遗传分化是外来入侵植物对生境异质性的两种适应策略；散布体多态型和散布途径多种化，使外来入侵植物迅速占领入侵生境，并进行远距离扩散；无性生殖和有性生殖并存，并根据生境和入侵阶段权衡的繁育对策不仅使入侵种群大面积暴发成为可能，而且直接影响散布机制并对种群遗传结构具有调节作用。

The genetic structure of Alternaria alternata Keissler was influenced by genetic background of host cultivar, and the genetic structure of isolates from different host cultivar was different.

赤星病菌的遗传结构也随寄主品种的不同而表现出一定的差异，寄主品种的遗传背景影响着赤星病菌的遗传结构。

It can be concluded from the experiment results that hatchery seed has lower genetic variation and large-scale hatchery seed releasing affects the genetic diversity of the natural population. The shrimp distributed along China coast in Bohai Sea and Yellow Sea may consist of more than one populations. The viral disease resistant ability of F. chinensis is proved to be genetically inherited and can be improved by genetic selection.

通过对实验结果的进一步分析认为：中国对虾人工育苗的过程使后代群体的遗传多样性下降，人工培育苗种的大规模放流影响了自然群体的遗传多样性；，分布于我国沿海的中国对虾可能由多个自然群体构成，还存在未被发现的种质资源；中国对虾抗WSSV病毒感染是由遗传决定的，选育可提高中国对虾对WSSV的抗性。

The result showes that The natural population of the wolf spider has abundant genetic diversity and there are difference in the genetic diversity of the population from different geographical regions.

结果表明：拟环纹豹蛛的自然种群具丰富的遗传多样性；不同生境的拟环纹豹蛛种群遗传多样性存在差异；海拔和积温是影响拟环纹豹蛛种群遗传分化的主要因子。

Thus the early biparental inheritance might be caused by occational male plastid transmission.

本研究在菜豆不同品种成熟花粉的生殖细胞中都没检测到细胞器DNA，表明父系可遗传的细胞器的排除在不同品种间是一致的，即不存在基因型的影响，我们认为菜豆的早期遗传分析得出的双亲遗传的结论可能是由于雄性质体的偶尔传递。

The observed matrilineal genetic structure is thus a reservoir that aggregated all kinds of genetic and demographic effects.

单一的历史事件虽然可能会在群体的遗传结构中留下痕迹，但目前观察到的群体的遗传结构反映的是一个很长的时间段内各种遗传效应和历史事件影响的综合。

The genetic behavior of these QTLs were investigated accordingto the performance of backcrosses.

5对以IR24为遗传背景的一套籼型渗入系进行了三地两年的详细考察，初步确认了各渗入系中所携带的渗入片段对抽穗期、株高、穗数、实粒数、总粒数、千粒重、单株重和结实率等性状的影响，并初步定位了11个重要农艺性状和产量性状QTLs，估算了这些QTLs的遗传效应，并在回交和测交中进一步确定了这些QTLs的遗传行为，讨论了渗入系在QTL精细定位与杂种优势机理研究中的应用。

The length of mandibular dental arch is controlled under weak genetic factors. Both maxillary and mandibular crowding are influenced by the environmental factors.

上下颌牙量大小和上颌牙弓弧长受较强遗传控制，下颌牙弓弧长受弱遗传控制，恒牙列拥挤度遗传度很低，受环境因素影响较大。

However, the mode of transmission is complex and non-Mendelian.

遗传因素对该疾病有很重要的影响，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。

Do you know, i need you to come back
