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。

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。

The results showed that MCW239 which in 2 chromosome and MCW260 which in 4 chromosome affected sigbificantly the Haugh Units of New Yangzhou chicken who were 60 weeks.

结果表明：与60周龄新扬州鸡的哈氏单位有关的标记为2号染色体上MCW239和4号染色体上的ADL260，与60周龄新扬州鸡的蛋重有关的标记为2号染色体上的ADL176和MCW239。

Objective: To analysis the aberration of chromosome 9 heterochromatin for persons suspected to have chromosome abnormalities.

文章摘要：目的分析疑有染色体异常个体的9号染色体异染色质区的变异。

Chromosomal analysis of skin cells from 8 tufted deer were studied by using primary culture and subculture.We found 4 different karyotypes in all and a new karyotype, different with the others studied before, was found. There were 47 chromosomes in somatic cell of the new karyotype, including a pair of heteromorphic X chromosomes, one was telocentric chromosome, the other was subtelocentric chromosome.

采用原代培养和传代培养方法对来自成都动物园的8头毛冠鹿的皮肤细胞进行了染色体研究，结果出现4种不同的核型，有一种核型与以前所报道的几种核型不一致，确定为新核型（2n=47♀，X染色体为异型，）。

Segregation distortions were found on chromosome 1, 2, 3, 6, 10, 11 and 12 respectively. There were some distorted markers clustered in special regions on chromosome 3, 6 and 11, and they all deviated toward indica homozygote.

不平衡分离发生在第1、2、3、6、10、11、12条染色体上，其中第3、6、11条染色体上发生不平衡分离的分子标记有「群集」的现象，且三者都倾向於秈稻同质结合型。

In the past century, people have devoted themselves to the worldwide problem——cancer, which does harm to people's health. Of late years, much research has been found that spindle checkpoint, which is a highly conservative mitotic watch system in the kinetochore of chromosome, has close correlations with chromosome instability and tumorigenesis.

近一个多世纪，人们一直在致力于攻克癌症这个危害全球健康的难题，近年来，大量的研究结果表明位于染色体动点上的一个高度保守的有丝分裂监督系统——纺锤体检验点，与染色体不稳定性及肿瘤的发生密切相关。

And the chromosome movements in mitosis are orchestrated by dynamic interactions between spindle microtubules and the kinetochore,a multi-protein complex assembled onto centromeric DNA of the chromosome.

有丝分裂过程中染色体的运动和分离又是通过纺锤体微管和位于染色体着丝粒上的动点之间的协同作用来完成的。
