遗传效应

The phenomena of which some genetic effects were spasmodically expressible were detected among filling stages of rice.

条件遗传分析的结果还表明一些遗传效应存在着发育时期间断表达的现象。

Secondly, we embedded a Legendre polynomial of 5 orders into fixed effects, additive genetic and permanent environment effects were characterized by using Legendre polynomials with from three to eight orders.

其次，固定效应镶嵌5阶Legendre多项式，加性遗传效应和永久环境效应分别镶嵌3到8阶的Legendre多项式。

Based on in comparison of all statistical criteria and behavior of estimated parameter the RRM with a fifth-order Legendre polynomial for both fixed effects and additive genetic effects, a seventh-order Legendre polynomial for permanent environment effects is equally well equipped to model all effects, which is the best model among different RRMs.

通过各种统计指标和估计参数行为的比较，确定固定效应和加性遗传效应镶嵌5阶Legendre多项式，永久环境效应镶嵌7阶Legendre多项式的随机回归模型为最优模型。

Protein content is important traits in evaluation of nutrient quality of rice. Most of crop traits are quantitative in nature, which are controlled by polygene. Its very important for rice nutrient quality breeding improvement to map quantitative trait loci of brown rice protein content.

蛋白质含量是评价稻米品质的一项重要指标，控制水稻糙米蛋白质含量的基因位点是数量性状，检测水稻糙米蛋白质含量的QTL并进行遗传效应分析对于水稻品质遗传育种具有重要的意义。

Micstructure and properties were investigated and dertermined. The results show that carbide structural inheritance of high chromium cast iron is obvious after remelt; carbide struc- tural inheritance was reduced with remelt times increasing; insulation can improve the carbide structural inheritance, but the longer insulation time was, the thicker ...

结果表明：高铬白口铸铁中的碳化物经过重熔仍存在明显的遗传现象；随着重熔次数的增加，碳化物组织遗传效应减弱，力学性能下降；保温处理可以改善碳化物的组织遗传性；过长的保温时间导致碳化物变得粗大，高铬白口铸铁的力学性能下降。

Although no changes occur in the genetic code, epigenetic effects can be passed to offspring.

虽然没有发生变化的遗传密码，遗传效应可以传递给后代。

A mispairing PCR-RFLP technique was applied in this study to determine the Insulin-like Growth Factor 2(IGF2) gene intron3 G3072A mutation in an outbred Landrace and Large White, and the gelded boars from Landrace×Large White cross. The difference of corresponding traits and the genetic effects of the boars inherited from parental A allele and inherited from parental G allele were analyzed.

采用错配PCR-RFLP技术鉴别了长白猪和大白猪纯种以及长白×大白猪杂交后代去势公猪胰岛素样生长因子2(IGF2)基因内含子3的3072位点变异，分析了遗传来自父本不同等位基因个体间的相关性状差异及不同等位基因的遗传效应。

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。

Molecular maker linkage map was construct with DH population derived from "Nong xi110×Nong xi531",and investigated the traits of 83 DH lines then quantitative trait loci associated traits related plant height were identified and analyzed,and discussed the molecular genetic mechanism, and offerred theory and referrence for improving the traits of plant height constitution.

本研究利用SSR标记构建基于组合&农系110×农系531&的分子标记连锁图谱，并对该组合的83个DH株系进行田间调查，分析控制玉米株型性状QTL位点与遗传效应，探索玉米株高构成性状的分子遗传机制，为玉米株高构成性状的遗传改良提供理论和参考。

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。
