交配

They painted the heads of some red males black. Then they mated those seemingly black-headed birds with both red and black females.

他们把几只雄胡锦鸟的红色头纹染成黑色，然后让这些看似黑色头纹的胡锦鸟分别与红色及黑色头纹的雌胡锦鸟交配。

So researchers played a trick on the animals. They painted the heads of some red males black. Then they mated those seemingly black-headed birds with both red and black females.

他们把几只雄性七彩文鸟的红色头纹染成黑色，然后让这些看似有着黑色头纹的七彩文鸟分别与红色头纹与黑色头纹的雌七彩文鸟交配。

Black-tailed gulls begin to countership and roost on the island ;in April they start to mate and build their nests. The peak period of laying eggs is from late April to early May, and then the parent birds begin to hatch.

三月份黑尾鸥开始求偶并在岛上栖息，四月份开始交配、筑巢，四月下旬到五月初为产卵高峰，随即成鸟开始孵化。

Also dependent on the park fall grasses, mosses, and shrubs are migrating birds and bull moose, which gather in their cows for the mating season.

还依赖于公园秋季草物，苔藓和灌木丛是候鸟和大型的驼鹿，那聚集一起的奶牛是因为交配季节。

This result is consistent with the result come from PCRfingerprinting method. The results of the two methods indicate that maize, soybeanand castor-oil plant can act as refuges of Bt sensitive cotton bollworm as non-Btcotton; while sesame and peanut may not.

第三代棉铃虫的六个寄主种群间存在一定的遗传差异；其中，花生种群与其他种群间没有明显的基因交流，遗传分化比较明显；Bt棉上的棉铃虫与普通棉花、大豆、玉米上的棉铃虫敏感种群间基因交流频繁；而与花生、芝麻上的棉铃虫敏感种群间的基因流均不显著，说明它们间有可能不能进行随机交配。

The results suggest that bothmaize and castor-oil plant could be refuge to provide susceptible individuals and toprolong the effectiveness of Bt-cotton, but peanut and sesame may not.

说明除普通棉花外，玉米、蓖麻能作为庇护所，提供Bt易感棉铃虫与抗虫棉上的棉铃虫个体随机交配，稀释抗性基因频率，防止棉铃虫对转Bt抗虫棉的抗性，而芝麻和花生不适于作为Bt易感棉铃虫的庇护所在田间与转基因棉花套种。

The 2.5-liter boxer four has been revised, putting out 170 hp and 170 lb-ft of torque, and will now be mated to a standard six-speed manual—up from a five-speed—or with Subaru's new chain-driven continuously variable transmission.

2.5升拳击四个已经修订，推出170马力和170磅英尺的扭矩，并且现在将交配，以一个标准的六速手动行动从5速或与斯巴鲁新连锁驱动无级变速。

In OWE-SOJ test, a fluffy colony without clampconnection formed in the A=B≠mating interaction where nuclear migration occurs, whilea barrage colony without clamp connection formed in A≠B= interaction where nuclearmigration do not occur. The two colonies could be distinguished clearly from each other.

而在OWE-SOJ试验中，发生核迁移的A=B≠交配反应形成无锁状联合的绒毛状菌落，而不发生核迁移的A≠B=反应形成无锁状联合的栅栏型菌落，两种菌落可以清楚地区别开来。

The research of XIE Baogui et al (2004) showed that fruit-body color of Flammulina velutipes is controlled by only one gene locus which is not linked with mating-type factor either A or B, and yellow color is dominance to white one.

谢宝贵等人(2004)的研究指出，金针菇的子实体颜色受一对等位基因控制，黄色为显性，白色为隐性，与交配型因子A或B不连锁。

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。
