查询词典 chromosome

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。
