广东省现有5个地方猪种基于SNP芯片的遗传多样性分析
Genetic Diversity Analysis of Five Cantonese Indigenous Pigs Based on SNP Chip
摘要
Abstract
The analyse of genetic diversity,genetic distance and population structure of the five Cantoness indigenous pig breeds were performed using SNP chip.The European,Asian wild boars and four commercial pig breeds were included in this study as controls.The results showed that XE,DHB,and LT pigs are low in genetic diversity compared with the western commercial pig breed,YDH and MH pig;Cantonese indigenous pig breeds had near genetic distance with Asian wild boars and large with western pig breeds;The MH pig,which was a subpopulation of DHB pig,has large genetic distance with the DHB,principal components analysis and STRUCTURE analysis showed the genetic difference between the two breeds,the MH pig has its special genetic structure and genetic introgression from the Western pigs was observed;The YDH pig has near genetic distance with the western pig breeds,genetic introgression from the Western pigs was also observed in the YDH pig.In conclusion,the XE,DHB,and LT pigs are low in genetic diversity,genetic introgression from the Western pigs was also observed both in MH and YDH pig.关键词
