查询词典 breeds

The average interspecific divergence was 3.860%, and special sites were found in each chicken breed which was the bases to identifying chicken breeds. The DNA taxonomy of Bar1 used NJ was consistent with morphological taxonomy among the six indigenous chicken breeds. However, the analysis of Bar2 sequences of COⅠindicated that they were lower polymorphism and no special site in most chicken breeds which was not benefit to identify chicken breeds. The DNA taxonomy of Bar2 used NJ was not consistent with morphological taxonomy among the six indigenous chicken breeds.

本研究选择的2段序列中，以Bar1序列648bp（712位点到1359位点）多态性最高，突变位点最多，为24个，品种间平均多态性为3.860%，6个鸡种在此序列中有各自不同的特异位点，NJ聚类分析6个品种基本被聚为不同的类别，与形态学分类基本一致，该COⅠ基因的Bar1序列用于这些品种鉴定是可行的；而Bar2序列进行序列多态性分析，由于其多态性低，大多品种没有其特异位点，NJ聚类分析6个品种基本被聚为不同的类别，与形态学分类基本一致，不利于品种鉴定。

By using the Neighbor-joining method, a dendrogram was obtained based on genetic distances. The bootstrap values were evaluated for each crunode of the dendrogram by means of bootstrap test. The results showed that the mean heterozygosity of the whole native egg-typing duck breeds population was lower than those of native chicken breeds and goose breeds, suggesting that the genetic diversity in those duck breeds population is relativly rare and should be strengthened. The rank of the heterozygosity was consistent with that of the polymorphism information content. The results of the genetic distances between them indicated that the differentiation occurred long time ago. In the dendrogram, Weishan pocked, Youxian pocked, Huainan pocked, Guangxi pocked and Jingjiang pocked were classified into one goup, Chaohuand Enshi pocked were the second group, Liancheng white, Putian black, Jinding, Shanma, Sansui and Shaoxing were the flnra grong.

结果表明：我国所有蛋鸭品种全部群体的平均杂合度较低，其遗传多样性相对贫乏，各保种场要加强多样性的保护；各品种的平均多态信息含量的高低与群体平均杂合度的顺序完全一致；遗传距离的计算说明了13个品种的遗传距离较远，分化时间较长；13个地方蛋鸭品种被聚类为3个类，微山麻鸭、攸县麻鸭、淮南麻鸭、广西小麻鸭、荆江麻鸭聚为一类；巢湖鸭和恩施麻鸭聚为一类；福建省的鸭种连城白鸭、莆田黑鸭、金定鸭、山麻鸭与三穗鸭、绍兴鸭聚为一类。

The results showed that the average heterozygosity was higher in 9 populations,the lowest is Jinding, the highest is San sheldrake, which ranged from 0.5137~0.6055. The average heterozygosity of 9 duck populations was 0.5523, which reflected the rich diversity. Considerable breed differentiation was observed and 25.65% of the total genetic variation came from breed differences, this result affirmed each breed was of own genetic diversity. The DA genetic distances suggested the longer differentiation existed between those breeds. The domestic duck breeds in East China were clustered into four groups based on the NJ clustering, the clustering results had some relationship with the distributions and economic utilizations of these duck breeds.

结果表明：9个品种的平均杂合度都较高，最低的为金定鸭，最高的为山麻鸭，杂合度范围为0.5137～0.6055，群体平均杂合度为0.5523，反映了各鸭种的杂合度都较高，遗传多样性丰富；华东区各鸭种间存在较大的遗传分化，25.65%的遗传变异来源于品种间的差异，更进一步反映了各品种具有本品种特征特性的多样性；通过计算DA遗传距离发现各群体的遗传距离较远，分化时间较长；NJ聚类结果将华东区家鸭资源聚为4类，NJ的聚类结果分析与几个鸭品种的地域分布和经济用途有一定关系。

Then,a very special haplotype il discovered in 27 Chinese cattle breeds, including 11 breeds in this study and 16 breeds in the GenBank,played the role of a nucleus in Chinese zebu and was further discussed.

云南牛品种的单倍型非常丰富证明了云南在中国黄牛起源上的重要地位；在27个中国黄牛品种中(本研究11个品种以及GenBank上的16个品种)找到了中国瘤牛的核心单倍型i1，并且对它进行了讨论。

The majority of pigs reared for meat in the UK are crossbreeds as described above. However the old traditional breeds still remain. The work of the Rare Breeds Survival Trust helps to support those breeds in danger of disappearing.

如上面描述的那样，英国大部分猪场饲养的主要是杂交品种，但不管怎样，一些古老的品种仍然保留，稀有品种保护中心的工作就是防止这些品种绝种。

Ma Lan can use seminal breed to also can undertake asexuality breeds already, emergence rate of direct seeding seed amounts to 85 ％ above, undertake with mature Ma Lan transplant breeds dividing individual plant survival rate is very high also.

马兰既可用种子繁殖也可进行无性繁殖，直播种子出苗率达85％以上，用成熟的马兰进行分株移栽繁殖成活率也很高。

In this research DNA Barcodes was based on the special section of the cytochrome c oxidase 1sequence. Three primers were designed in three special sections(Bar1 Bar2) to identify six indigenous chicken breeds. The Bar1 sequence of COⅠ(648 bp : from 712 sites to 1358 sites) was the highest in polymorphism and had 24 SNP in six chicken breeds.

本研究利用线粒体细胞色素C氧化酶I (cytochrome c oxidase ⅠCOⅠ)这一特定基因的特定区段来做DNA条形编码的基础，选择其中二段序列（Bar1 Bar2）设计2个引物对6个中国地方鸡种的线粒体DNA进行扩增，以对其进行种品鉴定。

The highest incidence is in toy breeds (Chihuahua, Yorkshire terrier, Manchester terrier, Pomeranian, toy poodle) and in brachycephalic breeds (English bulldog, Boston terrier, Pekingese, Lhasa apso).

The prolactin gene was studied as a candidate gene for the prolificacy of five different sheep breeds, namely small tail Han sheep (142), Hu sheep (40), Texel sheep (36), Dorset sheep (36) and Corriedale sheep (28). Single nucleotide polymorphisms of PRL coding sequence were detected among these five sheep breeds.
