Inferring the demographic histories of populations has wide applications in population, ecological, and conservation genomics. We present Stairway Plot 2, a cross-platform program package for this task using SNP frequency spectra. It is based on a nonparametric method with the capability of handling folded SNP frequency spectra (that is, when the ancestral alleles of the SNPs are unknown) of thousands of samples produced with genotyping-by-sequencing technologies; therefore, it is particularly suitable for nonmodel organisms.
推断群体的人口历史在人口学、生态学和保护基因组学中有着广泛的应用。我们介绍了 Stairway Plot 2,这是一个使用 SNP 频率谱进行此任务的跨平台程序包。它基于一种非参数方法,具有处理数千个样本的折叠 SNP 频率谱(即当 SNP 的祖先等位基因未知时)的能力,这些样本是使用测序技术进行基因分型产生的;因此,它特别适用于非模式生物。
