一种蛋白质，有特定的成釉细胞细胞制造，可以在牙齿的珐琅中找到，特别之处在于它的基因可以在X和Y染色体中找到，染色体位置：Xp22.1-22.3和Y。

It yields an accuracy rate of over 90% for X chromosomes, and over 80% for Y chromosome.

它会产生一个以上的X染色体，90％的准确率，超过80％的Y染色体。

In women, X chromosomes pair; in men, the X and Y chromosome pair.

To determine the true rate of aneuploidy and to elucidate the mechanism of aneuploidy,the sperms were decondensed for FISH analysis. It was found that the disomic frequencies of chromosome X was 0.208%. A new decondensation method was developed by trypsin treatment. The basic morphology of sperm was maintained.

为了解非整倍体的真实发生率及其发生机制，本文以X染色体α卫星DNA探针进一步检测出正常精子中X染色体的二体型频率为0.208％，同时，建立了一种保持精子基本形态的胰酶去凝聚的方法，为目前国内尚未开展的精子遗传物质结构的分子细胞遗传学研究，提供了新的手段。

In addition, the human X-specific and Y-specific whole chromosome painting probes were hybridized onto metaphase spreads obtained from male of Elaphodus cephalophus.No signals were detected, which indicates the phylogenetic relationship between human and the tufted deer is not close.

分别用人X、Y染色体特异的整条染色体涂染探针，通过荧光原位杂交的方法，检测核型Ⅰ中是否存在与人X、Y染色体同源的片段，结果显示该毛冠鹿间期、中期细胞都呈阴性，提示可能毛冠鹿与人的亲缘关系较远。

Secondly the product of the DOP-PCR of Y1,Y2,X+4,1 chromosome of Muntiacus crinifrons were used as the templates of the next amplification using the special primer devised according to the human SRY gene .

再以黑麂的Y1，Y2，X+4和1号染色体的DOP-PCR产物为模板，用人的特异性的SRY（sex determining region of the Y chromosome）基因引物对其进行扩增，结果表明黑麂只有Y2染色体出现了SRY扩增片段。

Compared the similarity and difference of distribution of homologous fragments on X and Y, we suggested that the sex chromosomes of spiny eel have evolved from a pair of homologous ancestral chromosomes, and during the evolution, a pericentric inversion might have occurred on the original Y chromosome, and subsequently terminal regional duplication might have followed, eventually resulting in the differentiation and formation of X and Y chromosomes, then the recombinants between sex chromosomes were repressed, so the sex chromosomes could be inherited steadily.

根据X、Y染色体上同源片段的分布的相似和相异，我们对刺鳅性染色体的分化历程进行了推测，即：刺鳅的性染色体起源于一对原始的同源染色体，通过原Y染色体上的一个明显的臂间倒位，以及染色体末端的异染色质成分的扩增，导致原始Y染色体与X染色体在染色体结构上的分化，从而抑制了X、Y性染色体之间的遗传物质的重组交换，为性染色体的稳定遗传奠定了基础。

To establish time-efficient and sensitive method for detection of the methylation of FMR1 and XIST genes,genomic DNA was deaminated by sodium bisulfite.

建立一种快速、灵敏的检测脆性X智障基因（fragile X mental retardation，FMR1）、X染色体失活基因（X chromosome inactivation，XIST）甲基化的方法。

Hemophilia B is an X-linked bleeding disease, caused by the mutations of human coagulation factor IX gene located in chromosome X. It results in a dramatic decline of hFIX quantity or clotting activity in plasma, and the intrinsic clotting pathway is affected seriously.

血友病B是一种性连锁隐性遗传病，其发病机制是位于X染色体上的人凝血因子IX基因发生了突变，导致血浆中hFIX含量或活性大幅下降，从而使得内源性凝血途径受到阻碍，无法进行正常的凝血。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
