个体交配

The gene targeted mice are commonly produced by breeding the heterozygous targeted mice following microinjecting the homologous recombinant ES cells into the blastocoele cavity of 3.5dpc embryos at the blastocyst stage to give birth to chimeric mice.

传统基因敲除获得某一突变基因的纯合体动物首先要利用打靶胚胎干细胞获得嵌合体动物；随后用嵌合体动物与野生型个体交配得到突变基因的杂合体动物；最后才能通过杂合体动物之间的交配来生产纯合体动物。

Snail is a hermaphrodite, and some type of independent reproduction, but most of the types of mating two individuals to exchange sperm.

蜗牛是雌雄同体的，有的种类可以独立生殖，但大部分种类需要两个个体交配，互相交换精子。

To produce by the mating of individuals of different breeds, varieties, or species; hybridize .

使杂交通过不同品种、变种或种类的个体交配而产生；使杂交

The panmixia hypothesis--that all European eel migrate to the Sargasso Sea for reproduction and comprise a single, randomly mating population--is widely accepted.

欧洲鳗鲡随机交配的假说—所有的欧洲鳗鲡个体都洄游到Sargasso海进行繁殖，组成一个单一并随机交配的群体—一直被广泛接受。

No significant relationship was found between the body sizes of amplexed males and females and successful male frogs were not significantly larger than unmated males.

结果表明：抱对雄蛙和雌蛙的个体大小无显著的关系，成功交配的雄蛙并不比未交配的雄蛙大，其它雄蛙不能取代已抱对的雄蛙。

I assessed if mating common eastern froglets Crinia signifera exhibited size-related patterns. I compared the snout-urostyle lengths and body condition of amplexing males with that of non-amplexing males to determine if successful males were larger or in better condition. I assessed if there was a linear relationship between the body length of the female and the successful male and the relative condition of the male (measured by body mass versus length).

通过比较抱对和非抱对普通东方小蛙的吻-尾干骨长和检测个体较大或状态较好的雄体是否为成功繁殖个体，检测雌蛙体长与交配成功的雄蛙的体长和相对状态之间是否存在线形关系，评估交配与个体大小之间的关系。

After the first mate, the male panda rests, watch and wait for the female panda to give another inviting signal. Then there comes the second or third mate.

雄性个体第一次交配后休息期间，雄性个体通过视觉见雌性出现待配姿势时，会立即起身进行第二、三次交配。

Mating success varies widely from bird to bird, with number of copulations per individual during the breeding season ranging from zero to several dozen.

鸟与鸟之间的交配成功率差别很大，个体在繁殖季节的交配次数从0到几十次不等。

A pairwise comparison of paternity studies of bird populations in relation to genetic variability as determined by minisatellite band sharing coefficients among unrelated individuals was used to test the prediction that females should engage more frequently in extra pair copulations in populations with a greater amount of genetic variation.

小卫星共有谱带系数(minisatellitebandsharingcoefficient)可确定无亲源关系个体之间的遗传变异性，对与遗传变异性有关的雄性个体的父亲进行了成对比较以检验如下假说：在具有较多遗传变异的种群中，雌性个体更经常地进行配偶外交配。

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。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
