We present here a novel method to estimate the site-specific relative variability in large sets of homologous sequences. It is based on the simple idea that the more closely related are the compared sequences, the higher the probability of observing nucleotide changes at rapidly evolving sites. A simulation study has been carried out to support the reliability of the method, which has been applied also to analyzing the site variability of all available human sequences corresponding to the two hypervariable regions of the mitochondrial D-loop.
我们在此提出一种新方法,用于估计大量同源序列中位点特异性相对变异性。它基于一个简单的理念,即比较的序列关系越密切,在快速进化位点观察到核苷酸变化的概率就越高。已进行了一项模拟研究以支持该方法的可靠性,该方法也已应用于分析与线粒体D环两个高变区相对应的所有可用人类序列的位点变异性。
