简单杂交

Based on analyzing the problems,we propose an evolutionary algorithm by using niches technology and multi-parent-crossover technology to experiment on complex multimodal function optimization with samples.

在分析了简单遗传算法求解带约束的多峰值函数优化中存在的问题的基础上，提出了利用小生境技术和多父体杂交的演化算法，对复杂的多峰值函数优化问题进行了测试，证实该算法能够快速求出多峰函数的所有全局最优解，而且搜索效率高，达到了令人满意的效果。

The new method combined the use of two DNA probes whose sequences comprises the whole complementary strand to the target DNA, in which one probe was labeled with an EDTA-〓 complex on the 5'-terminus and the other, labeled with a bidentate β-diketone on the 3'-terminus.

该法测定目标DNA的最低检测下限为6 pM，比现有其它均相DNA杂交分析法低2-3个数量级。该法具有简单、快速和高灵敏度等优点，通过使用各种的标记DNA探针，预计该法可广泛应用于各种实际DNA样品的分析。

The result suggested that different genomes had different genetic speed or stability during evolution.3 The similarities co-efficiency between wild emmer and hexaploid synthetic was higher than that between wild emmer and common wheat. So that crossing among species is not a simple combination of genomes, but involve introgression of chromosomes, and the evolution made by this action was bigger than that made by environment.4 According to the results of salt tolerance identification, the salt tolerance of wild emmer is lower than that of common wheat in the whole.

野生二粒小麦与普通小麦之间的遗传相似系数稍高于野生二粒小麦与其与节节麦合成的双二倍体的遗传相似系数，说明物种之间的杂交并不仅仅是染色体组简单的合并，其中包括复杂的染色体组本身的一些特性以及染色体之间的互渗且这种作用远大于环境作用所引起的变化。

Compared with hybrid transferring breeding, the radiation induced-mutation had advantages of simple method and short cycle.

辐射诱变与杂交转育方法相比，具有方法简单、周期短的优点。

His plan was simple – he injected a virus into the brain of a promiscuous vole.

他的计划很简单–他将一种病毒注入杂交田鼠的大脑。

In the past desirable properties were introduced into plants and animals through simple crossbreeding but for the most part scientists merely reshuffled genes within a particular species.

过去，理想的特性都是通过简单的杂交引进动植物的。但大多只是科学家们对某些特定的品种进行基因改组。

Northern blot analysis showed that the GFP gene was correctly expressed in the transgenic plants. Green fluorescence was observed in roots and immature embryos of transgenic plants by fluorescence microscopy.Progeny analysis showed that GFP insertions were inherited in T_2 generation with normal expression.Both Mendelian and non-Mendelian inheritances were observed in T_1 progenies of transgnic maize,and non-Mendelian inheritances were observed in T_2 progenies.

Southern blot结果表明GFP基因以低拷贝数、简单的方式(1～3条Southern杂交带)整合到玉米基因组；Northern blot结果表明GFP基因在转录水平上表达；在转基因植株的根和幼胚中观察到GFP表达；转基因植株的后代遗传分析表明GFP基因能够遗传至T_2代并正常表达，部分转基因株系中的GFP基因以孟德尔遗传方式传递给T_1代，但T_2代不符合孟德尔分离比。

It should NOT become a routine practice for all matings.

他不会变成一种简单的程序式的操作来应付所有类型的杂交。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
