The results showed that the hereditary mode of rolling tongue or pointed tongue is the dominant heredity of single gene of autosome,and the positive type of them is the dominant character;Twisting tongue is the recessive heredity of single gene of autosome,while the positive type is the recessive character.

采用Penrose先证者同胞法和分离分析方法对72个家系资料的分析表明：卷舌、尖舌均为常染色体单基因显性遗传，阳性为显性性状；翻舌为常染色体单基因隐性遗传，阳性为隐性性状。

The fragment size can be amplified by 295 bp through the primer, in order to prevent false positive from appearing, a pair of internal control primers C34 is designed through the invention according to a bull autosome 3 reported sequence, the fragment size is amplified by 208bp, dual PCR amplification is performed to single bull sperm through the two pairs of primers, and then the final evaluation is performed to the sperm separation purity according to the statistical analysis to the detection result.

本发明提供了一种检测X、Y精子分离纯度的引物，该引物是针对牛Y染色体上性别决定基因Sry通过PCR错配技术设计而成，通过该引物可扩增片段大小为295bp，为了防止假阳性出现，本发明根据牛3号常染色体报道序列设计了一对内标引物C34，扩增片段大小为208bp，通过上述两对引物对单个牛精子进行双重PCR扩增，然后根据对检测结果的统计分析，对分离精子纯度做出最终评价。

Interestingly, a monopolar spindle was assembled in each blastomere in the second cell cycle, and disjunction of duplicated chromosomes and the cleaage was preented, leading to the chromosome set doubling.

有趣的是，在第二个细胞周期中，每一个分裂球中都组装了一个单极纺锤体，同源染色体分离和卵裂被阻止，导致染色体组加倍。

The Mayo Clinic team led by Lisa Boardman, M.D., a specialist in gastrointestinal malignancies, investigated the structures inside of cells known as telomeres, which are the caps on the ends of chromosomes that keep chromosomes from unraveling.

Mayo临床研究小组由恶性消化系统疾病专家Lisa Boardman博士领导，该小组对细胞内部的端粒酶进行研究，端粒酶是染色体两端的帽状结构，它可以保持染色体结构的完整性。

Spermatogenesis is a complex process of cell division and differentiation resulting in a series of molecular and morphological changes in male germ cells.

精子发生是一个多阶段，多步骤持续的细胞分裂和分化过程，它受到性染色体和常染色体上一系列基因的调控。

In addition, a simple and fast algorithm is proposed to perform automatic detection of the centromere and axis of chromosomes.

此外，还进行了染色体G带带纹分割图像的着丝点和染色体的自动判别研究，提出了一种简单快速的算法。

Even without any prior model about chromosome, the centromere and axis can be determined rapidly.

在未使用染色体的先验模型的情况下，这种方法能快速而且比较准确地确定染色体的着丝点和中心线。

Having the centromere located near one end of the chromosome so that one chromosomal arm is long and the other is short.

近端着丝的着丝粒位于接近染色体一端的，因此染色体一臂长而另一臂短

The scientists found that human and chimpanzee X chromosomes are relatively similar.

科学家发现人类的X染色体同黑猩猩的X染色体较为相似。

Reach the poles, n the number of sub-chromosome, and each sub-chromosome composition of only one chromatid.

到达两极的子染色体为n数，并且每条子染色体只由一条染色单体构成。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
