| Outline of Final Research Achievements |
Molecular phylogenetic study on domestic process and global gene migration of chickens and pigs were carried out using mitochondrial DNA and single nucleotide polymorphisms as molecular markers. In phylogenetic tree of wild boars and pigs using SNPs, (1) separated clades were formed for each breed, subspecies or population, (2) Japanese wild boar (JWB) and Ryukyu one (RWB) separated into two clades obviously, and especially RWB had formed five clades in each island. In molecular analysis of chickens using mitochondrial DNA, it suggested the dual origins of African native chickens. The first group was probably originated from South Asia, and then migrated to West Asia, and finally arrived to Africa thorough Egypt. The second group migrated from Pacific to East Africa via Indian Ocean probably by Austronesian people.
Therefore, these obtained findings are important for the better understanding of the diversity and uniqueness of chickens (junglefowls) and pigs (wild boars).
