Discussion on Gene Sequencing and Classification of DNA Genetic Markers/关于基因测序与DNA遗传标记分类方法的论述

Author: Liu Huan (1983- ), Master of Science (First Class Honours), The University of Auckland

Nowadays, for the analysis of genetic similarity in species or subspecies by DNA sequencing technology, the selected DNA sequence fragments from gene bank only reveals a small part of the genetic information compared with the total genetic information contained by the whole genomes. Therefore, the significant difference derived from very limited/bias genetic information is likely to be a misleading conclusion. There are several reasons:

如今应用DNA序列片段对各物种或是亚种进行遗传相似性的分析技术中，其中所选用的DNA序列片段与整个基因组遗传信息总量相比，仅仅为其中的非常有限或是偏差性的遗传信息，因此所得出的显著性区别很可能是一种误导性结论。有以下三点理由：
