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。

Methods Amniocenteses were performed in 34 pregnant women of 16～23 gestational weeks with indications for prenatal diagnosis. The amniotic fluid samples were cultured in Chang's medium. The metaphase chromosomes were hybridized insitu with the human centromere probes,α-satellites DNA probes of X, Y,13, 21, 18 chromosomes and all primer chromosome probes. These probes were conjugated by Biotin and Dioxin then. The treated slides were examined and taken photos under the fluoromicroscope.

对34例孕16～23周有产前诊断指征者经腹部抽取羊水，用Chang培养液传代培养，常规制备羊水细胞分裂中期染色体，应用生物素及地高辛标记的人类全着丝粒探针和X、Y、13、21、18号染色体α-着丝粒探针及染色体全涂染探针，与培养的羊水细胞分裂中期染色体DNA进行原位杂交，杂交后用荧光显微镜观察玻片并摄像。

The results of measuring chromosome and one-way ANOVA analysis showed that the relative length of all autosomes was different among the sheep breeds.The X chromosomes were similar and the Y chromosomes were different not only in relative length p

测量染色体长度，计算相对长度，并进行单因素方差分析表明，绵羊各常染色体的相对长度之间存在一定的差异；对性染色体进行Duncan′s 多重比较，种群间X 染色体差异较小；Y 染色体种群间不但存在形态差异，且在相对长度上差异极显著P
