杂种的

When C.farreri×P.yessoensiswere tested by using6pairs of microsatellite primers which could be applied to boththe two kinds of scallops,the specific bands could be amplified fromeachone of the 6 pairs,among which,the specific bands fromboth agnate and maternal colony could be distinguished obviouslyinthe amplified products of P13F449 and KMY134,and accordinglythe hybrid identity of hybrid generations could be affirmed.

将这6对具有属间通用性的微卫星引物对栉孔扇贝×虾夷扇贝进行PCR扩增，均能扩增出特异性条带，其中引物P13F449和KMY134的扩增产物中可以明显地分辨出来自父母本群体的特有条带，从而确定了杂交子代的杂种身份。

While doing the RFLP tagging of giant embryogene,the genome changebetween mutants and its original parent,the relationship between RFLP andheteroses in indica,japonica and intermediate rice,the performance of multipleand null allelism in rice varieties,the utilization of null allelic RFLP probes inidentifying indica and japonica rice specifically,the distribution of the nullallelic RFLP probe RG684 in rice cultivars,and the segregations of RFLPmakers in indica/japonica F2 population were also studied.

本实验从经典遗传、分子遗传、育种潜力评估、育种新品系选育等领域，对巨大胚、甜胚乳、暗胚乳三种新型突变体进行了全面系统研究。在对巨大胚进行分子定位过程中，对涉及到的突变体与原始亲本基因组变化，籼、粳、中间型材料的RFLP多态性与杂种优势之间关系，水稻品种的复等位、零等位表现，鉴定籼、粳特异性的零等位RFLP标记，零等位标记RG684在稻种中分布，RFLP标记在籼粳交F2群体中分离等遗传现象也一并进行了分析。

To characterize the isotype of human xenoreactive nat ural antibodies against porcine pancrease islet cells, cyostat sections of the p ancrease were incubated with the sera from 18 cases of IDDM or 20 human controls respectively, further with FITC-conjugated goat antihuman IgG or IgM secondary antibodies. IgG was found to bind to pancrease islet cells in sera from 8 cases of IDDM and 8 human controls, while IgM in 4 IDDM and 6 human controls.

为检测人抗猪胰岛细胞天然抗体的同种型，采取18份胰岛素依赖型糖尿病患者血清及20份正常人血清分别与杂种猪胰腺组织的冰冻切片孵化后，再用免疫荧光标记的羊抗人IgG、IgM单克隆抗体染色。8份IDDM血清和8份正常人血清中含有直接针对猪胰岛细胞的IgG型抗体；4份IDDM血清和6份正常人血清中含有IgM 型抗猪胰岛细胞抗体。

Some discussions on essence,occurrence and change of BPH biotype were also provided

此外，致害力的纯化速度缓慢，容易发生衰退，显示的是数量性状的特征和某种程度的杂种优势。

Both of them, to be codominant markers, can identify false hybrids not only from selfed seeds of male and female but also from foreign pollen and mechnical contamination.

两引物均能在父母本中扩出特异带，为共显性标一记，不仅能够鉴别杂交种中混杂的母本自交的种子和父本的种子，还可鉴别部分由于外来花粉或机械混杂等造成的假杂种。

Three wheat spindle streak mosaic viruses resistant cultivars ('Yining Xiaomai', 'Xu87-633', and 'Xifeng') and one susceptible cultivar ('Zhen9523') were used as parents of 3 crosses in this experiment. WSSMV resistance of the parents, F1, and F2 was evaluated under field condition.

选用3个抗梭条花叶病的小麦品种&仪宁小麦&、&徐87-633&和&西风&为抗病亲本、以感病品种&镇9523&为感病亲本配制了三个杂交组合，对四个亲本及其杂种后代（F1及F2代）单株的田间抗病鉴定表明，三个抗病亲本的抗性均由核基因控制，为显性遗传方式。

It is feasible to forecast the heterosis of Small Tail Han Sheep crossed with imported meat sheep by genetic polymorphism of microsatellite DNA and it will have an important value for sheep breeding in future.

利用微卫星DNA 多态性预测引进肉用绵羊品种与小尾寒羊的杂种优势是可行的，将对今后绵羊育种具有重要的应用价值。

The trio's adoptive mother, a mixed breed farm dog called "Huani," is expected to nurse them for about a month or until their appetites outpace her supply, Chen said.

陈育才指出，这3胞胎的养母、称做「华妮」的农家杂种母狗，预定哺乳约一个月，或者直到它的奶水不足喂饱它们为止。

Seed purity can be tested easily as long as one primer of the last two types by RAPD; as to the first two types primers, two primers from both of them must be employed to test seed purity by RAPD.

利用一个互补型或杂合型的随机引物便可对杂种进行RAPD纯度鉴定，而另两种类型则须两个以上的引物才能得到可靠的鉴定结果。

Come on, you filthy, slimy mangy cur.

过来，你这个肮脏的，黏糊糊的，生满疥癣的杂种狗。

Do you know, i need you to come back

你知道吗，我需要你回来
