我们调查的实用程序的indel数据的系谱和群体遗传分析使用Tpi内含子的采叶蛾Acrocercops transecta（昆虫纲：鳞翅目）。系谱分析表明，插入缺失数据的同源性低于DNA序列数据，并且插入缺失数据包含足够的信号，以提供与从DNA序列估计的树高度一致的高分辨率树。虽然在多残基indel的分布中发现了一些冲突，但这种冲突对于重组的明确检测特别有用。首次采用贝叶斯聚类方法对该蛾的indel性状进行了遗传结构推断。我们的结论是，indel字符有可能成为一个强大的工具，在分析群体遗传学和群体结构，以及在检测基因流。(C)2011 Elsevier Inc.

We investigated the utility of indel data for genealogical and population genetic analyses using the Tpi intron of the leaf mining moth Acrocercops transecta (Insecta: Lepidoptera). Genealogical analyses revealed that indel data were less homoplasious than DNA sequence data and that indel data contained a sufficient signal to provide a high resolution tree that was highly congruent with the tree estimated from DNA sequences. Although some conflicts were identified in the distributions of multi-residue indels, such conflicts were especially useful for the unambiguous detection of recombinations. For the first time, we adopted a Bayesian clustering method for indel characters to infer genetic structure of the moth. We concluded that indel characters have the potential to be a powerful tool in the analysis of population genetics and population structure as well as in the detection of gene flow.
