杂交

The results of in situ hybridization show that cofilin1 mRNA express in oocyte.

原位杂交结果发现，Cofilin1 mRN在卵母细胞中有表达。

The results showed that during oogenesis, the positive signals of vasa RNA were detected in the cytoplasm of oocytes at all stages.

结果表明：在金鱼卵子发生中，在各个时期的卵母细胞的胞质中均有金鱼vasa RNA的杂交信号表达。

The vasa gene expression pattern during oogenesis of zebrafish was examined using in situ hybridization and fluorescent quantitative RT-PCR.

原位杂交结果表明：在卵母细胞生长、发育的过程中，第Ⅱ期卵母细胞的细胞质中vasa mRNA大量表达。

And it also showed that the inheritance of the growth-rate and pathogenicity to cotton seedlings of XC-6 could not be inherited steadily in zoospore progenies and oospore progeny, but the colony morphology and homothallic character of XC-6 could inherited steadily in both asexual and sexual progenies, which suggested that the inheritance and variation of the above characters might be related to long-selfing and hybridization in species.

同时，XC-6生长速率、对棉苗的致病力、菌落形态及同宗配合遗传和变异特性研究表明，其生长速率和对棉苗的致病力性状在单游动孢子后代和自交后代均不能稳定遗传，但菌落形态和同宗配合特性在单游动孢子后代和自交后代均能稳定遗传，提示上述性状在单游动孢子后代和自交后代的遗传和变异特性可能与菌株长期自交和种内杂交有关。

同时，XC-6生长速率、对棉苗的致病力、菌落形态及同宗配合遗传和变异特性研究表明，其生长速率和对棉苗的致病力性状在单游动孢子后代和自交后代均不能稳定遗传，但菌落形态和同宗配合特性在单游动孢子后代和自交后代均能稳定遗传，提示上述性状在单游动孢子后代和自交后代的遗传和变异特性可能与菌株长期自交和种内杂交有关。

This paper proposes a novel muiti-objective evolutionary algorithm, based on a novel crossover operation and improved crowding operation of NSGA-II ,in order to quicken further rate of convergence of solutions to Pareto optimal front and improve precision of solutions.

为了提高非劣解向Pareto最优前沿收敛的速度及进一步提高解的精度，本文在设计了一种新的杂交算子并改进了NSGA-II的拥挤操作的基础上，提出了一种基于分级策略的多目标演化算法。

Other habitat yellows such as Oribi Gorge are neither group 1 or 2, have red seed berries , superior flowers and umbels and produce only pigmented stems even when crossed but with spectacular colour forms.

其他原生黄花，比如ORIBI GORGE则既不是1系的，也是不2系的，这种黄花兰果实是红色的，有着非常高大的花束，而且在与其他花色品种杂交后只能繁殖出有色轴的子代。

Three hundred and twenty-four crossbred (Landrace×Yorkshine) barrows with average body weight of 27 kg were randomly assigned to 6 dietary groups: group Ⅰ(chlorotetracycline group, added 50 mg/kg chlortetracycline in basal diet); group Ⅱ(origanum oil group, added 20 mg/kg oreganum oil in basal diet); group Ⅲ(probiotics group, added 1.5 g/kg probiotics in basal diet); group Ⅳ(nutrient enhancement group, elevated dietary vitamin E, vitamin B family and micro elements Zn, Mn, I); group Ⅴ(origanum oil+nutrient enhancement group); group Ⅵ(probiotics+nutrient enhancement group).

试验选用平均体重27 kg，健康长×大杂交阉公猪324头，随机分为6组：Ⅰ组（金霉素组，在基础日粮中添加50 mg/kg金霉素）、Ⅱ组（牛至油组，在基础日粮中添加20 mg/kg牛至油）、Ⅲ组（益生素组，在基础日粮中添加1.5 g/kg益生素）、Ⅳ组（营养调控组，提高日粮中维生素E和B族维生素、微量元素Zn、Mn和I水平）、Ⅴ组、Ⅵ组。

DNA polym orphism of mainrestorer lines of hybrid rice in China.

我国杂交水稻主要恢复系的DNA 多态性研究。

The preserved species may lack genetic representativity because of poor sampling. Inappropriate plantations, inadequate records and unclear kinships jeopardize endangered species to genetic confusion, inbreeding depression or outbreeding depression.

由于引种或取样的不足，容易导致被保存的物种缺乏足够的遗传代表性；盲目的引种、不合理的定植以及材料的来源不清则会导致稀有濒危植物的遗传混杂、近交衰退或杂交衰退；人为选择和生长环境的改变也容易造成濒危物种对迁地保护的遗传适应。
