单倍的

The distributions of mitochondrial and chloroplast haplotypes imply that local drastic"founder effect"and"backcross" have played important roles in the establishment of the hybrid populations.

从线粒体和叶绿体单倍型的地理分布可以看出杂种群体的建立曾经历强烈的奠基者效应和回交。

On his 1997 track "Morphine"— an unusually discordant Jackson song — he sings,"Close your eyes and drift away Demerol ... Today he's taking twice as much Demerol."

在他1997年的单曲"吗啡"——一首并不怎么悦耳的歌曲中，他唱道，"闭上你的眼，随杜冷丁漂浮吧……今天他用了高两倍的杜冷丁。"

Options include automatic cable tensioning, single-acting models, cable tracks for greater load stabilization and capacity, a pulley arrangement to double the stroke and speed, caliper disc brakes on the cable pulley, and reed switches.

选配件包括自动钢索张紧，单动模型，用于稳定和增大载重量的钢索链条，可使冲程和速度翻倍的滑轮结构，钢索滑轮上的盘式刹车卡钳，以及簧片开关。

Direct sequencing of DNA amplified by PCR was used with the primers designed according to the sequence of control region and the neighbor region. Sequences were analyzed and compared base on Sequencing Analysis 3.4 and Seq/Ede software. DP of mtDNA in Yao ethnic group was calculated. MAGA2 software was also employed to analyze the genetic distance between samples and construct the phylogenentic tree.

以南方民族瑶族为研究对象，根据mtDNA控制区及周围区域的序列设计引物，用PCR产物直接测序对105份无关瑶族样本mtDNA控制区进行了测序，通过Sequencing Analysis 3.4和Seq/Ede软件分析比对，得到的序列结果，计算瑶族mtDNA单倍型的识别率，并应用MEGA 2软件对数据做进化距离分析，构建系统发育树。

Darwin, who hypothesised that all humans evolved from common ancestors in his seminal 1859 work "On the Origin of Species", came from Haplogroup R1b, one of the most common European male lineages, said genealogist Spencer Wells.

据系谱学家斯宾塞威尔斯介绍，达尔文是欧洲最常见的父系之一、单倍群R1b种族的后裔。达尔文在1859年出版的著名进化论著作《物种起源》中提出了"所有人类都是由共同祖先进化而来"的假设。

Furthermore, older haplotypes were detected in the two groups, respectively. Possible refugia are inferred in western Hubei Province and SW China during the glacial period.

我们在最小生成树的两个组中推断出一些古老单倍型，并推测在冰期时湖北和我国的西南地区可能是该物种的避难所。

The phylogenetic analysis of 22 ND4L sequences of Phocidae from GenBank showed that there are two clades (which belong to Northern Group and Southern Group) supported by relatively high bootstrap value and there are more closed relationship between spotted seal and harbor seal.17 haplotypes with 717bp were obtained from the mtDNA control region, adjacent proline and a portion of the threonine tRNA genes of 46 individuals.

利用从GenBank中下载的22个海豹科动物的ND4L基因序列的系统进化分析表明，海豹科动物分为南半球和北半球两大类群，斑海豹与港海豹为北半球种类，亲缘关系最近。从46个辽东湾斑海豹线粒体DNA控制区和苏氨酸及脯氨酸tRNA基因717bp片段的测序，得到17个单倍型。

Homozygosity for a haplotype that was identical by descent between two of the affected individuals identified a locus for the disease gene within a 17.4 Mb interval on chromosome 15, a region containing 296 genes.

对两个受累个体完全相同的遗传单倍型纯合性分析发现，疾病基因的基因座在第15号染色体17.4 Mb的区间内，该区域包含296个基因。

He built the MEG-1X personal strap-on helicopter rig which used a single-blade rotor with a tip-mounted G8-2 engine and followed this with the MEG-2X which had a two-blade rotor.

他建造了乙二醇- 1X的个人捆绑式直升机钻机的使用了单转子叶片用尖式八国集团- 2发动机，并遵循这一乙二醇- 2倍的有一两转子叶片。

In order to take full advantage of a uniparental marker system, such as mtDNA, we constructed a sufficiently resolved mtDNA phylogeny based on the information provided by the sequences of the control region and the coding region of 6 Han geographic populations, as well as information from published sources.

在分析了我国6个不同省份的汉族地理人群mtDNA控制区和编码区序列信息后，结合报道的全序列信息，我们建立了我国人群中mtDNA单倍型类群的系统发育关系。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
