Methods The DNA extracted from blood samples of unrelated individuals in Han population living in Jilin were amplified by PCR. The PCR products were analyzed by using PAGE.
方法利用PCR扩增和聚丙烯酰胺凝胶电泳技术对吉林地区汉族群体无关男性血样进行4个Y-STR基因座的分型。
Methods Genomic DNA was isolated from the venous blood leukocytes of 84 unrelated patients with chronic tic disorder (Study group) and 100 healthy unrelated individuals (Control group).
方法选取无亲缘关系的慢性抽动障碍患儿84例以及无亲缘关系的健康个体100例,后者作为对照组。
Objective To investigate the allele and genotype frequencies of DXS6804, DXS6799, DXS8378, DXS7130 and DXS7132 in unrelated individuals of Nu population and establish the related genetic database.
目的以云南怒族无关个体为研究对象,调查怒族群体DXS6804、DXS6799、DXS8378、DXS7130、DXS7132基因座的基因频率及基因型频率分布,建立群体遗传数据库。
The probability of two unrelated individuals of Chinese Han population having same sequence in the sequencing seament of D-loop region is 0.0068.
两个非血缘关系的中国汉族人出现完全相同序列的概率为0.0068。
