交配的

The results showed that different colour of male parent has no significant difference effect on feather autosexing accuracy rate of filial generation, while different colour of female parent has significant difference effect.

其中，不同羽色类型的公鸡与白羽中有大量红锈羽的母鸡交配，后代雏鸡自别雌雄准确率最低（79.3％）；不同羽色类型公鸡与纯白羽的母本交配，后代雏鸡羽色自别雌雄准确率最高（93.6％）。

One was the pqsA' positive expression plasmid constructed by cloning the pqsA'-lacZ fusion digested from pYHP441 into miniCTX-1, whose sequence was then integrated into wild type PAO-1 chromosome by biparental mating procedure. The other was pqsA-E operon knock-out plasmid whose sequence between pqsD and pqsE operon was inserted by tetracycline cassette by the site specific insertion mutagenesis strategy and the mutant constructed by biparental mating of S17-1 that harbored the plasmid and pqsA' positive expression mutant.

一种是酶切质粒pYHP441获得pqsA'-lacZ片段后，亚克隆入质粒miniCTX-1中，构建成PqsA'的阳性表达质粒，随后将构建的质粒，通过双亲交配过程整合入野生型铜绿假单胞菌株PAO-1染色体组中；另一种是通过点特异插入诱变策略，将四环素基因盒插入启动子pqsD和pqsE之间，构建的阴性质粒转化入大肠杆菌S17-1株后，和上述pqsA'阳性表达突变株进行双亲交配过程。

Sometimes a great many teeth or jaws are used, and they may be cut either circumferentially, so that they engage by cylindrical mating, or on the faces of the mating elements.

有时，一个伟大的许多牙齿或颌骨的使用，但他们很可能被削减要么环，让他们从事由圆筒形交配，或对所面临的交配元素。

This separation between the investment in copulatory plug and mating behaviour may be either a trade-off between traits in life history or a cultural behavior and need further investigation.

这种在交配栓上的投资和在交配行为投资之间的分离可能是生活史特征之间的一种权衡，也可能是一种文化行为，需要进一步研究。

Auricularia auricula is of the single-factor controlled mating system according to mating test among the F1 progenies and their parents, combining the method of dyeing the nuclei of the mycelia and observing the nuclear phase under the fluorescence microscope and the method of observing the clamp connection under the light microscope to determine whether the dikaryotic mycelia were formed.

摘 要：从黑木耳种内杂交子H2J3的子实体上单孢分离培养得到F1代52个单核体菌株，将F1子代及亲本(H2，J3)等所有供试单核体菌株的菌丝体两两配对培养，采用核荧光染色观察核相，和光学显微镜观察锁状联合，鉴别菌丝交配反应是否形成双核体菌丝，同时测定了亲本菌株所有F1子代的交配型。

After thirty-five generations, the two groups and their offspring were isolated reproductively because of their strong habitat preferences: they mated only within the areas they preferred, and so did not mate with flies that preferred the other areas.

经过35代，这两个果蝇群出现生殖隔离，因为它们有强烈的生境偏好：它们只在它们喜欢的区域交配，因此不与喜欢其它区域的果蝇交配。

Three hundred and twenty-five isolates of Magnaporthe grisea collected from rice plants in Wujiang, Yixing, Tongzhou, Gaoyou and Ganyu of Jiangsu province from 1997~1999 were tested for mating type and fertility with standard tester strains. Seventy-four tested isolates produced perithecia after mated with tester strains, in which, 48 were MAT1-1 and 26 were MAT1-2 mating type.

用标准菌株对1997~1999年在江苏省吴江市、宜兴市、通州市、高邮市和赣榆县采集的325个稻瘟病菌单孢分离菌株的可育性和交配型进行了测定，结果表明江苏省稻瘟病菌菌株的育性较低，可交配率为22.77%，可育率仅为7.08%。

Most toads mate in water - resulting in scaly black bumps on their hindlimbs which allow them to hold on to each other during mating, but the midwife toad mates on land - and therefore does not have these lumps.

多数蟾蜍在水中交配，这就使得后腿上的黑色鳞状突起物可以抓在其它蟾蜍的身上以进行交配，而产婆蟾则在陆地上完成，因为没有这类的突起物。

To support her argument, Dr. Brennan notes studies on some species that have found that forced matings make up about a third of all matings.

为了支持她的论点，布伦南博士研究指出，一些物种的发现，被迫交配约占三分之一的交配。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
