Abstract Text:

The pigs, Sus scrofa are independently domesticated from wild pig in many countries, which is one of the major livestock. It would be utmost important to know the relationship of livestocks with that of related wild ancestor for proper management of genetic integrity. We describe mitochondrial DNA control region based phylogeography among domestic and wild pigs representing various geographic locations of its range. Bayesian (MCMC) consensus tree showed two distinct lineages among Indian wild pigs. The main Indian wild pig lineage (S.s cristatus) showed distinct variation with that of east and north-east Indian wild and entire domestic pigs. This study indicated that the Indian wild pig, S.s cristatus is unique in its genetic feature and not used in domestication. However, the eastern and north-eastern wild pig’s populations are closely related to those of Asian and European wild and Indian domestic pigs.
