本文介绍了DNA条形码分析中常用的距离方法,包括简单的距离方法、基于阈值的距离方法和基于模糊成员关系的距离方法,并且以松毛虫属7个近缘种的COI数据为例,运用基于阈值的距离方法进行演示分析。
Three commonly used distance-based barcoding methods, minimum distance (MD), best close match (BCM) , and a fuzzy-set theory-based method are introduced and discussed. We demonstrate an application of the BCM approach to an empirical dataset from seven Masson pine moth species.
