遗传特征

the ancient dna, the most important genetic information of ancient human, has been widely used in the studies of human origin, evolution, racial character, migration and diseases, and herefrom the molecular archaeology has developed rapidly.

古dna是古代人类最重要的遗传信息载体，已用于人类起源、进化、族群特征、迁移、古代人类疾病等方面的研究，由此导致了分子考古学的兴起。

This study indicatd that specific MHC class Ⅱ alleles or haplotype may confer the susceptibility or resistance to IMN in shanghei chinese hsn, which conformed and developed the theory that IMN had an immunogenetic basis.

本实验结果表明，MHC-Ⅱ类某些特异性等位基因和单倍型可能授与上海地区汉族IMN患者易感性或抵抗性，并与临床特征及病理类型有关，论证并扩展了IMN的发病机制存在免疫遗传背景的推测。

The macronuclear and mitochondria DNA between the resting and the vegetative cell of Euplotes encysticus were comparatively analyzed by using RAPD technique in order to explore the acting feature of two genetic systems in the resting cell of ciliates.

为了探索纤毛虫休眠细胞中两套遗传系统的作用特征，对包囊游仆虫休眠细胞与营养细胞大核DNA和线粒体DNA进行了RAPD比较。

CAAT box" and "TATA box, potential regulatory motifs from transcription, and conserved cis-acting regulator elements were discovered within LTRs in the great number of sequences using plantCARE sortware.6 The insertional polymorphism of LTR-10 element within the genome of 8 wild species and 28 cultivars of Mallus Mill. was studied by sequence-specific amplification polymorphism.

分析获得的Tyl-copia类逆转座子的LTRs，其中含有启动子的结构特征&CAAT box&和&TATA box&及受不同胁迫条件作用的调控元件。6、基于苹果Tyl-copia类逆转座子LTR-10的SSAP技术在苹果属8个野生种和28个栽培品种中表现出了丰富的遗传多态性，多态性片段比例为88.2％。

First , girls' adolescence is between 7 and 19, which varies with themselves or matrilineal. That means, girls' first sexuality usually begin to develop when they are 7, sport and nutrition are two main factors that influence the adolescence most.

也就是说少女一般在七岁的时候女性的第一特征开始发育，当然也会因人而异，有的是遗传自母亲，有的也会根据自身的身体状况的不同而不同，主要是运动和营养两方面在起作用。

Furthermore, the experiences of artificial breeding and farming showed that different geographical populations of Meretrix clam are also substantially different in growth rate and the ratio of shell weight to soft-body one.

由于我国海岸线漫长、地形复杂，因长期地理隔离和生境不同，导致不同海域的文蛤在壳表形态和颜色、花纹图案等外观特征上均存在显著差异；另外，从多年的养殖实践中也发现，我国文蛤不同地理群体在生长速度、壳肉重比率等重要经济性状上也存在着显著差异，而这些性状的稳定性差异必然依赖于其分子遗传结构的变异。

Objective To analyze the phylogenetic relationship among four groups of Microtus fortis by gene distribution characteristics of ten biochemical loci.

目的观察四类东方田鼠在10个同工酶与异构蛋白生化基因位点上的基因分布特征，以研究它们间的遗传关系。

Objective To analyze the phylogenetic relationship among four groups of Microtus fortis by gene distribution characteristics of ten biochemical loci.

目的 观察四类东方田鼠在10个同工酶与异构蛋白生化基因位点上的基因分布特征，以研究它们间的遗传关系。

Meme, considered to be passed on by monogenetic unit, is defined as an element of culture.

被定义为一种过去的非遗传因素的模因被看作是一种文化因素，其主要特征就是模仿。

What we can conclude from the observation and seed-checking on morphic fectures of the treating group and comparison groups current generation and third generation is:apparent changes incurred to the leaf shape and the thickness of muskmelon when being treated by certain level of energy and dosage which can be inherited.

从各处理组与对照组当代和第三代苗期形态特征观察、考种中发现：在一定能量和剂量组合下，处理组香瓜叶型和果肉厚度发生了明显的变化，这种形态学变化是可遗传的。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
