We present an R package to help remedy the lack of software for manipulating and analysing autopolyploid and allopolyploid microsatellite data. POLYSAT can handle genotype data of any ploidy, including populations of mixed ploidy, and assumes that allele copy number is always ambiguous in partial heterozygotes. It can import and export genotype data in eight different formats, calculate pairwise distances between individuals using a stepwise mutation and infinite alleles model, estimate ploidy based on allele counts and estimate allele frequencies and pairwise F(ST) values. This software is freely available through the Comprehensive R Archive Network (http://cran.r-project.org/) and includes a thorough tutorial.
我们提出了一个 R 包，以帮助弥补缺乏用于处理和分析同源多倍体和异源多倍体微卫星数据的软件。POLYSAT 可以处理任何倍性的基因型数据，包括混合倍性的群体，并且假定在部分杂合子中等位基因拷贝数总是模糊的。它可以导入和导出八种不同格式的基因型数据，使用逐步突变和无限等位基因模型计算个体之间的成对距离，根据等位基因计数估计倍性，并估计等位基因频率和成对 F(ST)值。这个软件可以通过 Comprehensive R Archive Network（http://cran.r-project.org/）免费获得，并包括一个详细的教程。
