Genetic Structure and Maternal Origins of 8 Tibetan Goat Populations in Tibet Inferred from Cytb Gene Diversity
旨在基于Cytb基因多态性探讨藏山羊群体间遗传结构及其母系起源.对西藏8个地区157只藏山羊的细胞色素b基因(Cytb)全序列进行扩增和测序,分析群体遗传多样性,计算群体间遗传分化指数,构建系统发育邻接树等.结果显示,藏山羊Cytb全序列为1 140 bp,在8个群体中共检测到33个变异位点,定义了30种单倍型,单倍型多样性(Hd)和核苷酸多样度(Pi)分别为0.736和0.001 8,表明西藏地区藏山羊群体具有较丰富的遗传多样性.78.6％的群…查看全部>>
The aim of this study was to disclose the information of genetic structure and maternal origins of Tibetan goat populations based on the Cytb gene diversity.Mitochondrial Cytb gene of 157 individuals from 8 Tibetan goat populations in Tibet plateau areas were amplified and sequenced.The genetic diversity and genetic differentiation indexes were analyzed,and phylogenetic tree was constructed.The results showed that the length of Cytb was 1 140 bp,and 33 varia…查看全部>>
