A haploid cell that results from the meiotic division of an oocyte and becomes a female gamete or an ovum .

同卵双生的从同一受精卵中产生的，具有相同基因结构和相似外貌的孪生子的；单卵的

Meanwhile, Tibetan sheep (breeded in Sanjiaocheng of Qinghai, Huangcheng and Gannan of Gansu ), Mincounty Blank Fur sheep and Texel and Poll Dorset were controlled. The results indicated that polymorphism was tested at the loci of Hb, Tf and Es, that erythrocyte protein 1 and 2 were monomorphism. There were a couple of allele and three genotypes at the loci of Hb and Es. There were 10 genotypes at the locus of Tf, which was determined by 5 alleles.

结果表明，青海细毛羊和甘肃高山细毛羊的血红蛋白、转铁蛋白和酯酶基因座上存在丰富的多态性，其中Hb和Es位点受一对等位基因控制，共构成3种基因型；Tf位点受5个等位基因控制，共构成10种基因型；而红细胞蛋白质-1（EP-1）和红细胞蛋白质-2（EP-2）基因座均呈显单态；青海细毛羊的AMY基因座具有AMY1、AMY2、AMY3三种同工酶，其中AMY2呈多态，有AMY2A和AMY2O两种表现型，而甘肃高山细毛羊的AMY呈显单态。

Four sheep lines, HU-Yang, Chinese M erino monotocous, Chinese Merino multiparous for wool production and Chinese Merino multiparous for mutton production, were used in this study. Litter sizes were recorded for each ewe in the four lines. Primers for BMP15 and BMPR-IB gene were designed from database sheep sequence and polymorphisms were detected by PCR-RFLP method.

以绵羊BMP15基因和BMPR-IB基因为候选基因，以湖羊、中国美利奴单胎品系、中国美利奴肉用和毛用多胎品系为研究对象，采用PCR-RFLP方法对候选基因进行单核苷酸多态性位点检测和基因型分析，同时研究基因对绵羊产羔数的影响。

Odours co-ordinate a wide range of human behaviour. Mothers can recognise their children by smell. Children can recognise each other. Relatives can be distinguished from non-relatives, even to the extent of understanding who is genetically different enough from the smeller to be a good choice of mate. The sexes themselves smell different, too, and women can glean information about a man's social status from his smell alone.

很多人类运动是依靠气息来协调的：母亲可以通过气味来识别自己的孩子，而孩童之间的识别也借助这个媒质；是否拥有血缘关系也可通过其未来区分；甚至在配偶优选时可以通过气味知道对象基因的不同；女人单凭气味就可以搜集到一个男人的社会地位信息。

This method provided a rapid and accurate approach to the detection of pathogenic vibrios. In chapter three, broad-range PCR coupled with MCPC technology was adopted as a solution for broad-spectrum detection and identification of foodborne pathogens.

通过广谱PCR扩增食源性致病菌的16S rRNA和23S rRNA基因的保守区域，利用双链置换探针-MCPC技术针对扩增产物的差异序列区分不同产物，实现了在单管中对9类常见食源性致病菌的识别。

He merle gene is very common, and very popular, in the Australian Shepherd breed (they are sometimes called "those little blue dogs");,it is relatively common among Collies and Shelties as well.

产生双merle的唯一途径就是二只陨石繁殖。其结果，统计学上四分之一的宝宝为正常色，二分之一为携带单merle的陨石，另四分之一就是双merle基因的宝宝。

Ug99 could be called a superior virulent race to widely-used and Sr31-carrying Chinese wheat cultivars or stem rust resistant sources.The number of virulent genes contained in Ug99 was more than the total carried in all Chinese stem rust races.For instance,the virulence of Sr5,Sr9e or Sr11 was the typical races.However,besides the virulence of Sr5,Sr9e and Sr11,Ug99 contains additional virulence of Sr21,Sr31and Sr38,which have never been found in Chinese stem rust races.

Ug99堪称我国的超毒小种，我国最典型的秆锈菌小种只能分别克服或Sr5或Sr9 e或Sr11单基因抗性，而Ug99不仅具有Sr5、Sr9 e、Sr11的联合毒力，而且还具有Sr21、Sr31、Sr38的联合毒力，而我国从未有小种能克服后者的抗性。1B/1L(含Sr31)易位系曾是我国使用的重要秆锈抗源，必对Ug99高度脆弱，我国118份小麦品种在KARI的测定结果表明，高感品种频率98.3%。

YAO Jun-Feng, ZHANG Ying, WU Gui-Qin, ZHENG Jiang-Xia, DENG Xue-Mei, YANG NingCollege of Animal Science and Technology, China Agricultural University, Beijing 100094, ChinaSeven single nucleotide polymorphisms were identified by PCR-SSCP and sequencing in the chicken apoA5 gene in F2 chickens from an experimental cross of White Plymouth Rock × Silkies.

以丝羽乌骨鸡和隐性白洛克正反交产生的F2代为实验群体，采用PCR-SSCP和DNA测序的方法检测鸡载脂蛋白A5(apoA5)基因的单核苷酸多态性，并将所发现的SNPs与体重、胸肌重、腿肌重、心脏重、肝脏重和腹脂重等屠体性状进行关联分析。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.
