用h296DNA指纹图,经Southern印迹法,对12个家系中57名相关个体的DNA指纹图进行了检测。家系分析表明:各家系内成员DNA指纹图中各片段均按孟德尔分离律传递;亲属间片段平均共有率及片段一致机率,在一级、二级亲属与无关个体间有明显差异,并对其应用价值进行讨论。
Using h296 DNA fingerprinting, DNA fingerprinting of 57 related individuals in 12 pedigrees was tested by Southern blotting. The pedigree analysis showed that all the DNA fingerprints of each family member were transmitted by Mendel’s law of separation. The average share rate and the consistent rate of the fragment between the relatives were significantly different between the first and second degree relatives and the unrelated individuals Discuss its application value.
