Supplemental Material for Talebi et al., 2020

File S1 contains ROH segments per individuals. NSEG: number of ROH segment, KB: length of ROH per individuals, KBAVG: mean length of ROH per individuals, FROH: genomic inbreeding coefficient estimated from ROH. Table S1 shows summary of the number of ROH, mean ROH length per individual, and percent of coverage per autosome by chromosome in five populations of chickens. File S2 contains ROH islands identified in five chicken populations. Chromosome number, start and end position (bp) of ROH islands on chromosome, number of SNPs in corresponding region, size of ROH island, and details of gene information overlapped in ROH islands. File S3 shows the list of genes located within ROH islands and detected in multiple populations.文件S1包含各个体的纯合子片段（Runs of Homozygosity, ROH）相关数据：其中NSEG代表每个个体的纯合子片段数量，KB代表每个个体的纯合子片段总长度，KBAVG代表每个个体的纯合子片段平均长度，FROH代表基于纯合子片段估算的基因组近交系数。表S1展示了5个鸡群中每条常染色体的纯合子片段数量、个体平均纯合子片段长度以及染色体覆盖百分比的统计结果。文件S2包含在5个鸡群中鉴定得到的纯合子岛（ROH islands）相关数据，具体包括染色体上纯合子岛的编号、该染色体上纯合子岛的起始与终止位置（碱基对，bp）、对应区域内的单核苷酸多态性（Single Nucleotide Polymorphism, SNPs）数量、纯合子岛的长度，以及纯合子岛内重叠的基因信息详情。文件S3列出了存在于纯合子岛内且在多个鸡群中被检测到的基因列表。
