The Wuzhishan ant (MY) chicken exhibits significant differences from other chicken breeds. However, the molecular genetic relationship between the MY breed and other chicken breeds has not been assessed.
Whole-genome resequencing was used to compare genetic diversity, nucleotide diversity, the fixation index, the linkage disequilibrium coefficient, and phylogenetic tree relationships between the MY breed and the Wenchang (WC), Danzhou (DZ), Bawangling (BW), and Longsheng Feng (LF) breeds.
A total of 21,586,378 singlenucleotide polymorphisms and 4,253,341 insertions/deletions were screened out among the five breeds. The MY breed had the second highest genomic genetic diversity and nucleotide diversity and the lowest LD coefficient among the five breeds. Moreover, the phylogenetic tree analysis showed that individual birds of each breed clustered together with those of their respective breeds.
Our data indicated that the MY breed is distinct from the other breeds and can be considered a new genetic resource.
五指山蚂蚁（MY）鸡与其他鸡品种存在显著差异。然而，尚未评估MY品种与其他鸡品种之间的分子遗传关系。
利用全基因组重测序比较MY品种与文昌（WC）、儋州（DZ）、霸王岭（BW）和龙胜凤（LF）品种之间的遗传多样性、核苷酸多样性、固定指数、连锁不平衡系数和系统发育树关系。
在这五个品种中总共筛选出21,586,378个单核苷酸多态性和4,253,341个插入/缺失。MY品种在五个品种中基因组遗传多样性和核苷酸多样性第二高，连锁不平衡系数最低。此外，系统发育树分析表明，每个品种的个体与各自品种的个体聚集在一起。
我们的数据表明，MY品种与其他品种不同，可以被视为一种新的遗传资源。
