遗传影响

He writes of the "genetic fear" that percolates through generations, and the need to believe in bad rulers because the alternative, believing in nothing, could be worse.

他指出这种恐惧像被遗传了一样影响了一代代人，并且认为相信坏统治者也有其必要性，因为没有信仰，情况可能更为糟糕。

In this paper, male sterile line of alfalfa was used to be improved with crossing, because the seed production of crossing is low. The affecting factors of seed production of male sterile line of alfalfa and its crossing progenies that are crossed with male sterile lines of alfalfa and good alfalfa that male is fertile were analyzed. The characteristics of female reproductive organs of male sterile line and its crossing progenies are analyzed in cell morphology. The genetic difference of male sterile line and its crossing progenies are analyzed in enzyme protein. The results showed: 1、Rate of podding of nature crossing and fecundity of artificial crossing of the male sterile plant BC1-2 that is the crossing progency of male sterile line of alfalfa and Medicago varia Martin.cv.'Caoyuan No.1'is higher than male sterile lines. Rate of podding of nature crossing and fecundity of artificial crossing of the male sterile plants BC1-19、BC1-21、BC1-22、BC1-23 that are the crossing progencies of male sterile line of alfalfa and Medicago sativa L.cv.

针对苜蓿雄性不育系杂交制种产量低的问题，采用杂交法对苜蓿雄性不育系进行改良，以原苜蓿雄性不育系为轮回亲本与雄性可育优良苜蓿品种杂交，分析苜蓿雄性不育系及其杂交后代种子产量的影响因素，从细胞形态学方面观察和分析杂交后代及原不育系在雌性生殖器官上的变异特点，从酶蛋白水平对杂交后代及原不育系的遗传差异进行分析，初步研究结果如下： 1、苜蓿雄性不育系与草原一号苜蓿的杂交后代不育株BC1-2，以及苜蓿雄性不育系与X′(苜蓿雄性不育系与新疆大叶苜蓿的杂种F1代)的杂交后代不育株BC1-19、BC1-21、BC1-22、BC1-23的天然杂交结荚率和人工杂交制种的结荚率和百粒重均高于原苜蓿雄性不育系。

Also,the effects of estimation were dependent on structure of population size,accuracy of estimates would be decreased when number of sires was too few or data contained small number of animals.

同时，群体含量和结构能影响各种方法的估计效果，群体含量较小或资料来源的公畜数太少，将导致遗传参数的估计误差增大，准确性降低。

Effect of exogenous plant growth substance on the preharvest sprouting formation, endogenous phytohormones and related physiological and biochemical characteristic and agronomic properties were studied by spraying the exogenous GA3 and ABA on rice on the seventh day after tasseling, the results are as follows:Rice variety with high germinating potential is easier for preharvest sprouting.

穗上芽发生难易除种子自身遗传因子的影响之外，还与水稻种子自身内源激素GA_3和ABA含量密切相关，尤其与GA_3/ABA比值有关，易穗上发芽品种GA_3/ABA比值相对较高。研究表明，易穗上发芽水稻品种在穗萌到穗芽过程中α-淀粉酶活性、可溶性糖含量、可溶性蛋白和种子中含水量比不易穗上发芽的品种均相对较高。

From the statistical analyses of the descriptors used in the evolution procedure, three of them, including the partition coefficient (APlog98), indicator, E-State key were found to be the principal features affecting the biological activity, which supplies a guide for the design and reconstruction of new Ribonucleotide Reductase Inhibitors.

同时，通过分析在遗传优化过程中分子参数出现的频度，还得到了可能对活性影响较大的几个重要分子参数，它们分别是水／辛醇分配系数(ALogP98)、指示因子以及电性拓扑态指数。对该类抑制剂的设计和改造提供了指导。

Run cost to reduce the whole that supplies chain, reduce " long whip effect " influence, built multistage to supply the Mu Lti-agent model of catenary, use genetic algorithm is forecasted to its demand undertake optimizing study.

为降低供应链的整体运作成本，减小&长鞭效应&的影响，建立了多级供应链的Mu lti-agent模型，并运用遗传算法对其需求预测进行优化研究。

The content of acrylamide is subject to change by many factors, such as temperature, pH and humidity.
