这涉及到遗传学知识,就不在这里赘述了,直接上图吧。 1.首先解释什么是“血线”(这里用英文缩写是因为百度百科里是英文的):Genetic markers in the blood cell is called “blood marker”(Hm); Genetic Markers of DNA are used to identify diseases and health risk factors (Hp); Blood or tissue specimens that contain genetic information about specific genes are Hb,Hf,Hg等,简言之就是血液里的DNA片段,而基因在染色体里,即Chromosome,所以可以理解为从血液中提取的染色体的片段。
