interbreeding

Comparing the Altai genome to modern human DNA confirmed the interbreeding .

通过比较阿尔泰山脉尼安德特人的基因组和现代人类的DNA，确认了混种繁殖的存在。

Prolonged interbreeding in any species can eventually lead to serious birth defects .

长期来看，任何物种间的异血缘繁殖终会导致严重的先天缺陷。

However , harmful effects are more common in groups with a history of interbreeding over several generations .

但是，恶性先天缺陷常见于家族多代异血缘交配。

Once the scientists accepted that the interbreeding was real , they estimated when it happened .

一旦科学家们接受了混种繁殖的情况真实存在，他们就开始估算它发生的时间。

He defines the local population or deme as the group of potentially interbreeding individuals at a given locality .

他说地区的种群或居群是某一地区具有潜在杂交能力的个体的集群。

( biology ) relating to the occurrence of more than one kind of individual ( independent of sexual differences ) in an interbreeding population .

（生物学）关于混种人口中不只一种个体的存在（有别于性别差异）。

That genetic legacy is the result of interbreeding roughly 50000 years ago between Neanderthals and the common ancestors of Europeans and Asians .

这份基因遗产，是大约5万年前尼安德特人和欧亚人的共同祖先混种繁殖的结果。

The common origin of dogs indicated that the dog breeds were not generated by wolf domestication in different geography or interbreeding between wolves and dogs .

这也就否定了：不同品种的家犬是由不同地区的狼驯化而来，或者是与狼进行杂交形成的假说。

In a study published on Wednesday in Nature , a team of scientists reports that another instance of interbreeding left Neanderthals in Siberia with chunks of human DNA .

在《自然》杂志（Nature）周三发布的一篇研究论文中，一组科学家提交的案例表明，混种繁殖使得西伯利亚的尼安德特人带有部分人类DNA。

Eventually , however , Dr. Castellano persuaded him the data were strong , and Dr. Viola looked over the fossil record for possible explanations for the interbreeding .

不过，卡斯特利亚诺最终说服他相信数据是可靠的。于是维奥拉博士查看了或许可以解释这一混种繁殖的化石记录。

They show that Neanderthals split from our human ancestors about 500,000 years ago and evolved separately , with little or no interbreeding , until Neanderthals became extinct 28,000 years ago .

这些成果显示，尼安德特人大约在50万年前从人类祖先中分离出来，独自进化。此后，他们几乎或根本没有与其它族群杂交繁衍，直至2.8万年前灭绝。

The researchers further concluded that the Manot specimen " provides important clues about the morphology of modern humans in close chronological proximity to a probable interbreeding event with Neanderthals . "

研究者还进一步得出结论，认为马诺特标本“为现代人类在与尼安德特人发生可能的交配活动前后的形态学特征提供了重要线索”。

Every goldfish today , despite their varied looks , are descended from the wild gibel carp , and interbreeding will result in fertile fry since they are genetically identical .

今天所有的金鱼，除了长相不一，都是由野生银鲫进化而来，因为它们基因相同，杂交会产生很多鱼苗。

The discovery team urged caution on the interbreeding issue , but noted anatomical features of the cranium suggesting that some human-Neanderthal mixture had presumably occurred before any encounters in Europe and Asia .

发掘小组的科学家强调在交配假说的问题上需要慎重，但指出，头盖骨的解剖学特征表明，一些智人与尼安德特人混合的迹象可能在这两种人在欧洲和亚洲相遇前，就已经出现了。

Mr Malfoy submitted his demand for a ban on the story in writing : Any work of fiction or non-fiction that depicts interbreeding between wizards and Muggles should be banned from the bookshelves of Hogwarts .

马尔福先生提交了要求取缔这个故事的书面申请：任何描绘巫师和麻瓜通婚的虚构或非虚构类作品，都应该禁止出现在霍格沃茨的书架上。
