交配

In the nineteenth century, the most widely credited example was that of lord morton's mare, reported by the distinguished surgeon sir everard home, and cited by charles darwin.[4] lord morton bred a white mare with a wild quagga stallion,[5] and when he later bred the same mare with a white stallion, the offspring strangely had stripes in the legs, like the quagga.

在19世纪时期，被引用最多的例子来自lord morton的母马，是被外科医生everard所发现的，后来又被达尔文引证。lord morton把一匹白色母马和一匹种斑马交配，而后他又将同样一匹母马与一匹白色种马交配，它们的后代奇怪地在四条腿上带有条纹，就象那匹斑马。

Lthough August Weismann had expressed doubts about the theory earlier, it did not fall out of scientific favor until the 1890s, when a series of experiments by James Cossar Ewart in Scotland and other researchers in Germany and Brazil failed to find any evidence of the phenomenon. The result obtained by Morton could probably be caused by the display in the offspring of the recessive genes inherited by the Morton's mare from her parents or grandparents

ugust Weismann对理论表示怀疑(也就是你回应提到马交配的实验，在本段的上半部有提及我就不引用了)但这理论始终得到学界支持，直到James Cossar Ewart在苏格兰，德国，巴西所做的系列实验都无法发现有关现象的根据；Morton观察到的，可以说是马遗传了亲代或祖父母的隐性基因，并表现出性状也就是最初实验马交配发表先父遗传的人

Now we are seeing the pretty rare Lion-tiger animal who came from Korea, the generation of a female lion and male tiger. They can copulate because they belong to felid, but the child of them cannot raise anymore and has no biology value. There are only 10 lion-tigers in the world, and the surviving ratio is just 3‰.

现在我们看到的是极其罕见的狮虎兽，它产自韩国，是由雄性狮子和雌性虎交配后所产的后代，因同属猫科动物所以能达到交配，它同马和骡子杂交的后代骡子一样，并不具有下一代繁育的能力，并没有生物学价值，全世界狮虎兽只有10余只，成活率是千分之三左右。

If a male donkey is bred with a female horse, they produce a mule. If a male horse is bred with a female donkey, they produce a hinny.

如果一头公驴同一匹母马交配，生下的是"mule"；如果是匹公马同母驴交配，生下的是"Hinny"。

Artificial hybrid The offspring of the crossing between two species that would not interbreed in nature, produced in aquaculture or aquarium conditions.

人为杂交将二个在自然中不会交配的物种在人为环境下交配，以增加后代物种的形态表现。

The average thrusting duration was 20.9±0.5 seconds,and the average mating duration was 45.2±1.3 seconds.4 There was no copulatory lock during mating,and the male usually ejaculated following a single intromission after several thrusts.

平均抽动持续时间为20.9±0.5s，平均交配持续时间为45.2±1.3s.4东北虎在交配过程中无锁结现象，雄虎通常在一次爬跨多次抽动后即出现射精。

It were analyzed DNA polymorphism in baby rats between outbred Wistar and SD rats with 30 microsatellites DNA loci of PCR amplification. And was breeding baby inbred rats using high and middle of Coefficient of similarity with female SD rats of F0. It was indicated that there were hybrid and polymorphism loci, there weren't homo-gene loci of F2. It were monomorphism homo-gene for 27, rate of homo-gene loci for 90%.

利用PCR扩增30个微卫星DNA位点对封闭群SD和Wistar大鼠交配繁殖的仔代鼠进行微卫星DNA多态性分析，仔代中与母代SD大鼠相似系数高的与中的进行定向交配繁殖。F2代大鼠均为杂合多态的位点，没有纯合位点；到F9代时基因纯合位点达27个，纯合基因位点率为90%。

Negative assorative mating occurs when dissimilar phenotypes breed together, leading to OUTBREEDING.

反向选型交配则发生在不相似的表型在一起生育时，可以导致异系交配。

The author studied the changes in estradiol in female urine, mating behavior and factors influencing male mating investment in maske palm civet by using radioimmunoassay technique behavioral sampling techniques, and got the following results and conclusions

笔者使用同位素放射免疫分析方法研究了雌二醇在雌性果子狸繁殖中的变化过程、使用随机取样法和所有事件取样法研究了果子狸的交配行为和影响雄性果子狸交配投资的因素。得到以下结果和结论

This pattern of genetic structure implies non-random mating and restricted gene flow among eels from different sampled locations, which therefore refute the hypothesis of panmixia.

这种遗传结构暗示非随机交配模式和不同区域样品间存在一定限制的基因流，因此否认了随机交配假说。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
