目的为了初步探讨2个位于2号染色体的短串联重复序列(short tandem repeat,STR)位点在广东汉族人群中的遗传多态性。方法应用毛细管电泳技术和五色荧光复合扩增的方法,对156名无血缘关系的广东汉族个体使用ABI310/3130全自动测序仪进行STR基因型分析。结果在156名汉族人群中,D2
Objective To investigate the genetic polymorphisms of two short tandem repeat (STR) loci on chromosome 2 in Guangdong Han population. Methods The genotypes of 156 unrelated Guangdong Han individuals were analyzed by ABI310 / 3130 automatic sequencer using capillary electrophoresis and five-color fluorescence multiplex amplification. Results in 156 Han Chinese population, D2
