遗传影响

Molecular genetic research reveals that some endogenous ge nes in plants are responsible for parthenocarpy, even that some genes derived from bacteria can regulate the production of plant hormones.

分子遗传研究表明，植物基因组中含有影响单性结实的基因，某些来自于细菌的基因也可在植物激素生物合成途径中起调节作用。

The authors proposed that heterochromatin change in genome might play an important role in balancing the germplasms between maize and its distant relatve after cross and parthenocarpy.

这种变异不仅存在于表型不稳定的早代孤雌系中，而且还存在于表型稳定的高代系中，造成这种变异的原因可能是因为远缘种质的引入影响到遗传平衡进而引起染色体发生结构重排并引起染色质的变化，这种变化与玉米染色体组中非同源染色体间存在的同源片段和因此造成的减数分裂过程中非同源染色体配对有着直接的关系。

And the relationship between the closest factor related to yield and genetic distance was evaluated by partial correlation analysis.

最后将杂种优势中对产量影响最大的因子分别与RAPD及SSR标记的亲本间遗传距离进行偏相关分析。

Penetrance can be influenced by mutation-specific phenotypes and the potential modifying effects of the patient's own genetic and environmental background.

外显率则受突变特异表型和病人自身的遗传和环境背景潜在的修复效应所影响。

Genetics can influence the pharmacokinetics and pharmacodynamics of drugs at different levels.

遗传能影响药物在体内不同水平上的药物动力学和药效学。

This method can be used to family data to analyze the effects of genetic factors and environmental factors to qualitative phenotype.

该方法可应用于家系资料，分析遗传因素和环境因素对质量表型的影响大小。

Genetic dissection of QTLs for yield traits were further conducted for the genomic regions harboring Pi25. It was found that two or more linked QTLs for yield traits were located in this region, and they had effects on each of the 6 yield traits studied. It remains unclear that the genetic drag between Pi25 and yield QTLs was solely resulted from unfavorable linkages, or partially ascribed to pleiotropism of Pi25.

应用2期2重复的小区产量性状鉴定试验，进一步剖析产量性状QTL，发现Pi25两侧区间影响所有6个产量性状，且该区间存在2个以上控制产量性状的不同基因座，但尚无法判定研究群体存在的遗传累赘是全部源于抗病基因与产量性状QTL的不利连锁，还是部分源于Pi25的一因多效。

A clear understanding of genetic factors and environmental influences that predispose to NAFLD/NASH is needed.

对于遗传和环境因素对于NAFLD和NASH的发病的影响，需要有一个清晰的认识。

Previous studies suggest that stereotypy is a result of interaction between genetic predisposition and environmental effects.

前人的研究结果表明，行为规癖的表现是遗传上的倾向性和环境影响共同作用的结果。

The probability vector can be viewed as a prototype vector for generating solution vectors that have high evaluations with respect to the available knowledge of the search space. Compared with the general genetic algorithm, PBIL discards the complex and problem-correlation operators, which always affect the algorithm's performance highly.

相对于常规遗传算法，PBIL进化算法抛弃了复杂的且对算法性能影响很大的交叉、变异算子，而引入竞争学习的机制，以概率矢量的方式通过采样来产生下一代群体，然后选出群体中最优个体对概率矢量进行更新，直至最后收敛。

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％。
