Primary Analysis of Mitochondrial DNA D-loop Region Sequence in Baoshan Pig
云南保山猪线粒体DNA D-loop区序列初步分析 Primary Analysis of Mitochondrial DNA D-loop Region Sequence in Baoshan Pig

To investigate the genetic diversity and genetic data of Baoshan pig in Yunnan province,the mitochondrial DNA D-loop hypervariable segment I sequences 15 363 approximately 15 801 (438 bp) in 19 individuals of Baoshan pig were sequenced. Ten mitochondrial haplotypes were identified in the samples, with 8 sites showing polymorphism, which were 5 T/C and 1 G/A transitions, 1 G/C and 1 A/T transversions. The contents of A,T,G and C were 35.4%,26 9%,13.2% and 24.5%,respectively. The content of A+T (62.3%) was significantly higher than that of G+C (37.3%). It will be of importance to conservation and sustainable utilization in Baoshan pig.
