查询词典 x chromosome

The decomposition of chromosome was a main problem in construction of BAC library. DNA discompose would be avoided or decreased by adjustments of component and pH of chromosome extraction buffer or pre-electrophoresis for 6-8h before digestion. Identification of inter-species hybrids was a necessary step for creating a new germplasm. Two samples were selected from offspring of hybridization and backcross of a cross between cabbage and Chinese cabbage.

鉴定种间杂种是利用远缘杂交创造新种质时的一项重要工作，本研究运用细胞核DNA含量流式测定技术，对甘蓝和白菜杂交及回交各世代的DNA含量进行检测，以监控遗传物质在不同材料间的流向，并从回交二代植株群体中筛选了两个材料，具有和白菜差异不显著的DNA含量，可推断其为核质杂种。

Emmer crossed with another 14-chromosome goat grass to make bread wheat, an even plumper 42- chromosome grain that did not scatter in the wind, but must be planted.

它与另外具有14个染色体的假升麻草杂交便生成我们做面包的饱满颗粒，但它必须人工加以种直

The aim of study was to investigate the importance of chromosome aberration in differential diagnosis of eosinophilia and the chromosomal aberrations involved in patients with clonal eosinophilia. 65 cases of eosinophilia were collected and chromosome specimens of bone marrow cells were prepared by 24hour culture, and Gbanding technique was used for karyotyping.

为探讨染色体异常克隆在嗜酸性粒细胞增多症诊断和鉴别诊断中的意义及克隆性嗜酸性粒细胞增多症涉及的染色体异常，收集了65例嗜酸性粒细胞增多患者的骨髓标本，培养24小时，采用G显带进行核型分析。

Aneuploid cells with chromosome numbers less than 30 were discovered in 6 varieties. The study proved that the basic chromosome number was very stable and extreme climate might be the inducing reason for the euploid and aneuploid.

为此本研究特对广西、广东茶区共10个茶树品种的染色体数目进行观察分析，以期完善这一区域茶树品种资源细胞学的研究，并为指导茶树育种实践提供细胞学依据。

Result It was found in the results that the better pretreatment time for onion root-tip was 3.0 h and its better dyeing solution was basic fuchsin dyeing solution. On this basis, it was found that the chromosome number of tested onion was 2n=2x=16 through chromosome karyotype analysis on the root-tip cells of onion.

结果］结果发现，洋葱根尖的较好的预处理时间为3.0 h，较好的染液为碱性品红染液；在此基础上，通过洋葱根尖细胞染色体核型分析，发现试验所用洋葱的染色体数为2n=2x=16。

It was wared the direct relationship of chromosome pericentric inversion and bad gravidity and aciesis by removing the factor of immunization an endocrine for chromosome pericentric inversion.

因此在排除了免疫、内分泌等因素造成的流产后，对于染色体臂间倒位，应注意其与不孕不育、流产的直接关系。

Using the methods of classical shape size measuring and chromosome analysis, we studied the morphological characters and Karyotype of Cobitis sinensis in Xiangjiang River. We also investigated the evolution line and Karyotype polymorphism of the C . sinensis by the methods of cytological classification and cytocatalytic. Our results suggest that the formation of chromosome polymorphism was concerned with heterologous hybridization and some of C . sinensis may perpetuate in a clonal manner by natural gynogenesis.

本文以湘江流域的中华花鳅为研究对象，运用经典的形态测量观察方法、染色体制片技术对中华花鳅的形态生态特征、染色体组型进行了初步研究：运用细胞分类和进化方法对中华花鳅的核型演化和核型多态现象的形成进行了分析，提出：其核型多态的形成牵涉到鳅科鱼类的异源杂交，某些中华花鳅可能是行雌核发育生殖的。
