主要家养动物（家鸡）基因组重测序数据（2020-2022）

为描述青藏高原及周边地区（泛第三极地区）主要驯化动物遗传多样性的分布格局，厘清其相关遗传背景。2020年我们对266个全球家鸡血液、组织等DNA组织样品提取总DNA后建库并做全基因组测序，同时下载已公布家鸡基因组数据一共863个家鸡基因组开展群体分析，为探索泛第三极地区家鸡驯化、迁徙、扩张等群体历史事件提供基础数据，并进一步探讨驯化动物对干燥等恶劣环境的适应机理提供资料。本数据集相关文章已发表，本数据集内所有数据提供fastq，bam，vcf，snp文件在线下载。

To characterize the distribution patterns of genetic diversity of major domesticated animals in the Qinghai-Tibet Plateau and its surrounding areas (Pan-Third Pole Region) and clarify their underlying genetic backgrounds, we conducted the following work: In 2020, we extracted total genomic DNA from 266 global domestic chicken samples including blood and tissue specimens, constructed sequencing libraries and performed whole-genome sequencing. Additionally, we downloaded 863 publicly available domestic chicken genome datasets to conduct population genomic analyses. This dataset provides fundamental data for exploring population historical events such as domestication, migration and expansion of domestic chickens in the Pan-Third Pole Region, as well as supporting resources for further investigating the adaptive mechanisms of domesticated animals to harsh environments like arid conditions. Papers related to this dataset have been published, and all data including fastq, bam, vcf and snp files are available for online download.
