tab delimited file with data used in Figure 1. Contains Population (state code), genetic marker, alleles per locus (mean-centered), population size, log of population size, squared log of population size, alleles per locus, mean alleles per locus (for each marker) and sample size for each population.本文件为制表符分隔格式数据集，包含图1所用的相关数据，具体包含以下字段：种群（州代码）、遗传标记、经均值中心化处理的每一位点等位基因数、种群规模、种群规模的对数值、种群规模对数的平方、每一位点等位基因数、各标记对应的平均每位点等位基因数，以及各群体的样本量。
