全面了解中国乌骨鸡的遗传背景有利于保护和开发利用其种质资源。本研究测定了中国12个乌骨鸡品种线粒体细胞色素c氧化酶亚基I (cytochrome c oxidase subunit I,COI)基因,比较分析其遗传多样性和群体遗传结构。 255份乌骨鸡样品共检测到22个变异位点,占分析位点的3.17%;核苷酸多样性为0.00142-0.00339,单倍型多样性为0.380-0.757,其中略阳乌鸡核苷酸多样性最高,德化黑鸡最低。检测到7个氨基酸变异位点,来自6个品种共11个个体。定义了24种单倍型,其中单倍型H1和H3为12个乌骨鸡品种共享,出现频率分别为115次和64次;盐津乌骨鸡单倍型数最多,广西乌鸡最少。中性检验与错配分析显示实验种群未经历显...

Comprehensively evaluating the genetic diversity of Chinese black-bone chickens will facilitate conservation and utilization initiatives for this invaluable genetic resource. Mitochondrial cytochrome c oxidase subunit I (COI) gene sequences were obtained from 12 black-bone chicken breeds in China. These sequences were then used to analyze the genetic variation and population structure. A total of 22 mutation sites were detected from 255 individuals representing 3.17% of all sites. The nucleotide diversity and haplotype diversity ranged from 0.0...
