set31.Zupdated.autoANDchrZ.ALLSHARED.SNP.derFreqs.csv

Derived allele frequencies for each population sample at each variable site for which there was a high-quality genotype call for all 31 individuals, and the outgroup species were fixed for the ancestral state. Columns with the suffixes "_1" and "_2" give the allele frequencies for sample subsets of two individuals, used for calculating the denominator of the fraction introgression f statistic. Values were calculated using the script freq.py. Values for Z and autosomes were calculated separately due to ploidy differences between the sexes, and then the outputs were combined.

针对所有31个个体均获得高质量基因型判定的每个可变位点，且外类群物种在该位点的祖先状态呈纯合固定的情况，本数据集提供了每个种群样本的衍生等位基因频率。后缀为"_1"和"_2"的列对应由两个个体组成的样本子集的等位基因频率，用于计算基因渐渗f统计量的分母项。所有数值均通过freq.py脚本计算得到。由于两性间存在倍性差异，Z染色体与常染色体的统计值分别计算后再进行合并。
