They are usually spotted as nothing more than a blue flash beside the river but one patient photographer has captured the rare moment these pair of amorous kingfisher's decided to fornicate.

汉考克斯捕捉到翠鸟交配的照片令许多喜爱翠鸟的英国人松了一口气。由于今年冬季的严寒，许多人担心这种美丽的鸟儿会被冻死，数量会大大减少。

This is how bald eagles prepare to mate -- by locking talons and free-falling like rocks -- which is deeply insane and makes me proud to call the eagle my country's national bird.

这就是秃鹰准备交配的方式--抱成一团，如同那石块一样自由落体--一种疯狂直至的方式，它让我自豪地把鹰称之为我的国家的国鸟。

In a large, randomly mating population that is free of disturbing forces, allele and genotypic frequencies do not change and are related in a simple way.

在一个大的，随机交配的人口是免费的令人不安的力量，等位基因与基因型频率不改变，并在有关的一个简单的方法。

As for the Nepionic Rats at the body growth characteristic of different days ages,the method of observing the distance and the relative distance of the anus and the vulvas when they were three to four days old was used to discriminate the sex.When they are five to eight days old,the method of observing the papillas was added to discriminate the sex.

将同期交配的孕鼠分为4组，针对乳鼠在不同日龄的身体发育特点，在3～4日龄采用观察其肛门与外阴距离和相对距离的方法、对5～8日龄再附加对乳头观察的方法进行性别鉴别对比实验。

Methods The pregnant rats mating in the corresponding period were divided into four groups.As for the Nepionic Rats at the body growth characteristic of different days ages,the method of observing the distance and the relative distance of the anus and the vulvas when they were three to four days old was used to discriminate the sex.When they are five to eight days old,the method of observing the papillas was added to discriminate the sex.

Six hundred ova were transfered into twenty-nine pseudopregnant recipients. Fifty-five offspring were born from the ova mircroinjected with the Bcl-2 fragment expression cassette.Twelve of them were proved to be gene integration positive by PCR .Four founder mice,two male and two female ,were further confirmed to be transgenic by Southern hybridization.

用BglII+SalI+PvuI三酶切pWBS和用BglII+BamHI双酶切pWCS，分别回收并纯化3.0kb的基因片段WAP-Bcl-2-SV40polyA和3.5kb的基因片段WAP-c-myc-SV40poly，作为目的基因，通过受精卵显微注射技术，分别导入C57BL／6J雌鼠与DBA／2J雄鼠交配的F1代小鼠受精卵的雄原核中，各注射约1000枚，将存活的受精卵各600枚分别移植至29只假孕母鼠输卵管壶腹部内。

These included "lizards in their skin, birds with beaks and eyes, spiders with their webs, and frogs copulating."

其中涉及&皮肤上的蜥蜴纹、长喙和眼的鸟、带网的蜘蛛、交配的青蛙&等内容。

The up-close and personal meeting with the mating pair of Kingfishers, was snapped last week by wildlife photographer Mark Hancox who waited beside the River Severn in Worcestershire for five weeks, in order to get his prized shot

比如1962到1963年间的冬季非常寒冷，英国90%的翠鸟因严寒和缺少食物而死亡。不过捕捉到翠鸟交配的照片，表明这种鸟儿的数量会逐渐恢复。据估计，去年在英国境内共有约3300到5000对翠鸟。

In this experiment, Jacob et al analyzed the progeny from matings that are interrupted after different intervals, using different Hfr strains in which F has integrated in different places. Then, it became both conceptually and practically possible to map genes in E. coli simply by measuring and comparing time of transfer.

在此实验中，Jacob等使用不同的Hfr菌株，分析了不同时期被间断交配的细菌子代，根据不同基因被转移的次序绘出大肠埃希菌染色体基因图谱。

From July 17 through July 23, 2009, APHIS, in cooperation with the California Department of Food and Agriculture and the Los Angeles County Agricultural Commissioner, confirmed the detection of four male and one mated female OFF's on three separate residential properties in the La Verne area.

从2009年7月17日到7月23日，检疫局、加州食品农业部和洛杉矶县农业专员，确认在拉维恩三个独立的住宅物业区发现了桔小实蝇的四头雄虫和一头交配的雌虫。

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。
