Abstract:
Objective To analyze the Cyt b gene sequences in Tibet mini-pigs and clarify the differences and genetic relationship with other Chinese pigs.Method The sequence of Cyt b gene was amplified from genome DNA of Tibet mini-pig,Bama miniature pigs,Guizhou xiang pigs and Wuzhishan (WZS) pigs.After sequencing,the base sequences were compared and analysed.The blood relationship tree and evolution position of Tibet mini-pig were established.Result There were 14 mutation sites between domestic pigs in China and pigs from Europe.Besides there was a significant differenee in two nucleotide site:a T→C switch in site 420 and the G→A switch in site 883 at the same time.Conclusion Chinese pigs include Bama miniature pigs,Guizhou xiang pigs and WZS pigs,have a very close blood relationship with some of Tibet mini-pigs.It has been confirmed that there is a certain genetic differentiation in the Tibet mini-pig.
