和田羊线粒体DNA D-loop区序列研究
Study on Mitochondrial DNA D-loop Sequence of Hotan Sheep
摘要
Abstract
[Objective] This study aims to analyze Hotan Sheep genetic diversity by using mitochondrial DNA D-loop sequence.[Method] This experiment obtained Hotan sheep mtDNA D-loop sequence by sequencing and after that,it was compared with those of the Tibetan sheep,Mongolia sheep,Kazakh sheep and Bashibai sheep included in the Genbank.[Result] The results indicate that Hotan sheep 's mtDNA D-loop sequence is l184bp and four copies of a repeated sequence with 75 bp.Cluster analysis displays that the gene of Hotan sheep is close to that of the Tibetan sheep and far cry from that of the Kazakh sheep.Homology analysis result and the analysis of genetic distance are the same.[Conclusion] Hotan Sheep is close to Tibetan sheep in genetic distance,and they share high homology,which might be caused by the geographical distribution of the two varieties.关键词
