交配的

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

Factor hybridism and two2factors hybridism.

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。

Of unmixed blood or ancestry.(10) Genetics Produced by self-fertilization or continual inbreeding; homozygous

近亲繁殖的，同族交配的：由自体受精或持续的近亲交配而产生的；同型结合的

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。

From July 9 through July 22, 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, one mated female, and one unmated female white striped fruit flies on various residential properties in the La Verne and San Dimas areas.

从2009年7月9日到7月22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四头雄虫、一头交配的雌虫和一头不交配的白色条纹雌性实蝇。

The index of pleonal expansion (ratio of inter-tergite distances to thoracic length) was significantly different among female reproductive conditions; females with spermatophores just before egg extrusion had the most expanded pleon. In the mating trials, all females showing index values higher than 0.35 mated with males.

腹部宽度指数在雌蟹生殖条件指数具有明显的不同；有精荚的雌蟹在产卵前具有最宽的腹部；在交配实验中，所有与雄蟹交配的雌蟹指数值均高于0.35。

The lowest Fst value shows that less genetic variations exist among population of F.gracilipes whic is close to panmictic There is almost no genetic differentiation between populations of F.statice . Genetic similarity is 55.3%~ 65.2% between species of F.tataricum and its related species, which is close to the average level among species in seed plants.

这些种的近交繁育系数 F 值-0.54～-0.80，为随机交配的居群，杂合体过多；营养繁殖为主的金荞麦的FST值最高，相对较多的遗传多样性存在于居群间，长柄野荞麦相对较少的遗传多样性存在于居群间，更接近于自由交配。

We determined net male genetic effects on female and offspring fitness in a seed beetle and then tested whether fertilization success was biased in favor of high-quality male genotypes in double mating experiments.

研究人员惊奇地发现，当雌性豆象与2个雄性豆象交配的时候，那个&低品质&的雄性豆象的精子会比&高品质&豆象育出更多的后代（用仅交配一次后所产生的后代的数量来衡量）。

The three young leopards from the North - Hlabankunzi, Metsi and Xikavi - have all been mating with the Tegwane male yet again. These frequent matings might continue for a while until such time as these three young females have established themselves in a territorial area.

在北部， Hlabankunzi，Metsi和Xikavi三只年轻雌豹都与雄豹Tegwane有交配的行为，他们频繁的交配可能会持续一段时间，直到这三个年轻的雌豹建立自己的领土为止。

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。
