The genetic structure and evolutionary relationship of Dulong chicken with other native Chinese species remained unclear. In this study, the mitochondrial control region was analyzed in total of 343 samples comprising 59 from Dulong chicken and 284 from 8 other Chinese local breeds revealed 51 mutation sites that defined 42 haplotypes. The maximum genetic variation was observed between the Shimian caoke and Pengxian yellow chickens. Phylogenetic analysis revealed that these local chickens mainly scatter in two southwestern clades. Dulong chickens have close relationship with other native chicken. Finding of this study suggests a single matrilineal lineage of indigenous Dulong chickens.
独龙鸡与其他中国本土鸡种的遗传结构和进化关系尚不清楚。在本研究中，对总共343个样本的线粒体控制区进行了分析，其中包括59个独龙鸡样本和来自其他8个中国地方品种的284个样本，共发现51个突变位点，定义了42个单倍型。石棉草科鸡和彭县黄鸡之间观察到最大的遗传变异。系统发育分析表明，这些地方鸡主要分布在两个西南分支中。独龙鸡与其他本土鸡关系密切。本研究结果表明独龙鸡存在单一的母系谱系。
