The median network of Tibetan pig and other pig mitochondrial DNA (mtDNA) based on the sequence variation in the control region. The mtDNA control region fragment covers the region from 15,372 to 15,414 relative to the AF486859 reference sequence. These samples are from the nine populations of Tibetan pigs in five provinces, including Linzhi, Shannan, Changdu, and Rkaze pigs from the Tibetan Plateau area; Aba and Ganzi pigs from Sichuan Province; Hezuo pigs from Gansu Province; Diqing pigs from Yunnan Province; Qinghai pigs from Qinghai Province; and other pig breeds. Each haplotype is represented by a circle, with the area of the circle proportional to its frequency. Samples from different regions are indicated by different colors. The length of each branch is proportional to the number of mutations on the respective branch. In parentheses are the haplotypes we named, which are the same as the reference haplotype in Larson’s article.
