In the article, we used PCR-gel elec-trophoresis method to determine the number of repeat of P ( CGG) n. We have 126 normal X chromosomes and 18 X chromosomes obtained from fra ( X) families.

采用PCR凝胶电泳法测定126条正常人群X染色体及来源于脆性X综合征家族的18条染色体的P（CGG）n重复数目。

Methods Implicating intron 19 of the factor ⅷ gene of 6 patients with the hemophilia A and 207 unrelated X chromosomes were amplified by PCR and were analysed by means of Amp RFLPs of Hind ⅲ.

方法用PCR扩增6个甲型血友病患者家系和207条无亲缘关系的X染色体的Ⅷ因子基因19内含子，用HindⅢ酶切进行Amp－RFLPs分析。

From what you eat and drink to where you live, there's a special sickness lying in wait just for you if you have the misfortune to have two X chromosomes.

如果很不幸你的基因是由两个X染色体组成，那么从你吃喝的东西到你生活的地方，这儿都有个专门的疾病在静静地等待着你。

The X chromosomes in XO females are all type M. Hence, the reproductive capacity of XO females may be related to the X ( M) chromosomes.

XO雌体中的X性染色体为M类型。所以XO雌体的生育能力可能与X（M）染色体有关，其上可能存在雌性育性基因。

Results: In five abnormal sex-differentiation cases. We found that three of them had red signals, which represented Y chromosomes, while two presented green signals meaning X chromosomes.

结果发现5例性分化异常患者中，3例标记染色体为代表Y染色体的红色信号，另2例标记染色体为代表X染色体的绿色信号。

But female cats already have two X chromosomes so they can own that coat without the extra X, which means Venus is not necessarily a chimera.

但雌猫已经有两条X染色体，因此它们即使没有额外的X染色体也能有这样的皮毛，也就是说，双面猫不一定是嵌合体。

In each karyotype, X chromosomes. were 2N and Y chromosomes Were 1N.

在每个核型中X染色体均为2N，Y染色体为N。
