交配的

On our program this week, we will tell about an animal that can reproduce without mating.

在本周的节目里，我们会向您介绍一种不需要交配便可以繁殖的动物。

You need to find as many prospective homes as possible for your babies before the mating takes place.

在你让小熊交配之前，你必须尽可能多的找到一些愿意收养他们的人。

However, outcrossing may be abandoned in favor of parthogenesis or selfing (which retain the advantage of meiotic recombinational repair) under conditions in which the costs of mating are very high.

然而，在交配代价很高的条件下，异型杂交可能被摒弃，从而有利于孤雌生殖或自交（它们保留了减数分裂重组修复的好处）。

Olfaction plays crucial role in mosquito host seeking, oviposition and searching for sugar sources.

嗅觉在蚊虫的吸血寄主搜寻、产卵和糖源搜寻行为中起决定作用，而在交配行为中的作用并不清楚。

Generally, whether the panmixia ratio is large or small, the population reaches to equilibrium after 1-10 generations.

普通群体依据随机交配率大小的不同，趋近平衡的时间不同。

When the panmixia ratio vary from 0 to 1, its influence on the genotype frequency are lessening, as for inbreeding coefficient, it is constant.Ninth.

并且随机交配率从0到1对基因型频率影响的程度由大逐渐变小，近交系数对基因型频率影响的程度始终一样。9。

Mathematical model 3.7, 3.16 and 3.30 are the mathematical model of a equilibrium population, and they can be converted into mathematical models of panmixia population and nonequilibrium selfing population.

它可以转换为随机交配群体的数学模型和非平衡自交群体的数学模型。

When population are in noneequilibrium, if we know the genotype frequency of one generation of common population, the genotype frequency of the next or any generation can be calculated on the basis of the panmixia ratio and gene frequency directly.

群体在非平衡条件下，如果已知普通群体某一世代的基因型频率，根据随机交配率、基因频率可直接推算下一代或任一世代的基因型频率。

To date, the panmixia hypothesis has remained unchallenged: genetic studies realized on eel's mitochondrial DNA failed to detect any genetic structure; and a similar lack of structure was found using allozymes, with the exception of clinal variation imposed by selection.

到目前为止，随机交配假说尚未得到挑战：通过线粒体研究未发现鳗鲡存在遗传结构，而利用同工酶也得到缺乏遗传结构的相似观点，而因选择引起的渐变群变异是例外。

Pemberton said that in the past, mating was restricted to a three-week period around March and April, the southern autumn.

潘伯顿表示，过去袋獾只在三、四月间有三周的交配期，这段期间是南半球的秋天。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。

Designed by French fashion house Herm è s, this elegant uniform was manufactured in our home, Hong Kong, and was the first without a hat.

由著名品牌 Herm è s 设计，这件高贵的制服是香港本土制造，是我们第一套不配帽子的制服。
