mtDNA indices of Philippine domestic pigs and mainland Southeast Asian pigs.

Phylogenetic relationships of Philippine domestic pigs and wild pigs with continental domestic pigs and wild boar.
The number indicated in the nodes were probability support with warthog as the outgroup. Probability supports lower than 50% were not shown. Philippine domestic pigs revealed to comprised founder sources from five different geographic origins excluding the endemic Philippine wild pigs.
Fig 4.
The median-joining network of Asian and European pig haplotypes including the global reference sequences showing haplogroup classification.
Some haplotypes clustered together coinciding with their geographic area of origin, while selected haplotypes diverse and shared by individuals of different breeds from different geographical regions, indicating a negative correspondence between the geographic origin and the relationships among breeds. The size of each circle is proportional to the haplotype frequency. Color represents regions of sequence origin.
