Moreover, the sex difference of male and female Pistacia Vera can be clearly identified through observing chromosome and analyzing karyotype, but the operation of this technique is difficult.

此外，进行染色体压片技术及核型分析可以直接清楚地了解雌雄株的性别差异，但技术难度大。

This approach is valuable for genes whose existence is implied by genetics, but whose nature is unknown. One example is the gene zfy located on the human Y chromosome. Figure 2.17 shows a zoo blot using a probe from this region. It hybridizes specifically with sex chromosomes of mammals and also with

这个方法对于那些通过遗传学已证明存在的，但其性质还未知的基因是很有效的，例如人Y染色体上的zfy基因，它可以和哺乳动物或其它一些物种的性染色体杂交，且包含一个可译框，于是证明它是一个保守基因。

In Klinefelter's syndrome however, due to one of nature's accidents, when the male sperm fuses with the female egg, the fetal cells have at least one extra X chromosome. The most common number of chromosomes found in KS is 47, that is 44 autosomes and 3 sex chromosomes giving a karyotype of 47,XXY.

在克氏综合徵，但由於一大自然的意外，当男性的精子导火索，与女性卵子，胎儿细胞有至少一个额外的X染色体是最常见的染色体数目，发现在堪萨斯州是47 ，这是44 autosomes和三性染色体给予染色体核型47 ， xxy 。

It was found that the sequences amplified from the CHD-W gene using primers P2、P8 were more conservative, the sequences amplified from the CHD-Z gene had many variation, and that the length of Z chromosome had polymorphyism during the sex identification of Chinese Egret.

发现引物P2、P8扩增的CHD-W基因的片段较为保守，而扩增的CHD-Z基因片段变异较大，而且在对黄嘴白鹭的性别鉴定过程中发现Z染色体长度多态现象。

The stage which is most sensitive to high temperature is trachea colouring embryo(ji-3), while the stage sensitive to dry condition is body pigmentation embryo(ji-5), so these two development stages have been called high temperature sensitivity stage and dry condition sensitivity stage respectively. The gene of high temperature and dry condition sensitivity is defined as sex-linked temperature sensitivity gene, which exists in 21.5 location of Z chromosome linking closely to sch gene, and presents concealed heredity.
