To clarify the biological relationships between the Edo Ainu and other populations, their haplogroup frequencies were compared with those of 14 ancient and modern‐day East Asian and Siberian populations obtained from previously published data (Adachi et al, 2011; Lee et al, 2006; Maruyama, Minaguchi, & Saitou, 2003; Sato et al, 2009; Schurr, Sukernik, Starikovskaya, & Wallace, 1999; Sekiguchi et al, 2008; Starikovskaya, Sukernik, Schurr, Kogelnik, & Wallace, 1998; Starikovskaya et al, 2005; Sukernik et al, 2012; Tajima et al, 2004; Xu & Hu, 2015; Yao, Kong, Bandelt, Kivisild, & Zhang, 2002).

ObjectivesThe Ainu, the indigenous people living on the northernmost island of Japan, Hokkaido, have long been a focus of anthropological interest because of their cultural, linguistic, and physical identity. A major problem with genetic studies on the Ainu is that the previously published data stemmed almost exclusively from only 51 modern‐day individuals living in Biratori Town, central Hokkaido. To clarify the actual genetic characteristics of the Ainu, individuals who are less influenced by mainland Japanese, who started large‐scale immigration into Hokkaido about 150 years ago, should be examined. Moreover, the samples should be collected from all over Hokkaido.Materials and methodsMitochondrial DNA haplogroups of 94 Ainu individuals from the Edo era were successfully determined by analyzing haplogroup‐defining polymorphisms in the hypervariable and coding regions. Thereafter, their frequencies were compared to those of other populations.ResultsOur findings indicate that the Ainu still retain the matrilineage of the Hokkaido Jomon people. However, the Siberian influence on this population is far greater than previously recognized. Moreover, the influence of mainland Japanese is evident, especially in the southwestern part of Hokkaido that is adjacent to Honshu, the main island of Japan.DiscussionOur results suggest that the Ainu were formed from the Hokkaido Jomon people, but subsequently underwent considerable admixture with adjacent populations. The present study strongly recommends revision of the widely accepted dual‐structure model for the population history of the Japanese, in which the Ainu are assumed to be the direct descendants of the Jomon people.

MtDNA control region sequence polymorphisms and phylogenetic analysis of Malay population living in or around Kuala Lumpur in Malaysia

et al. 2009

Control region polymorphisms in the mitochondrial DNA of 124 unrelated individuals from the Malay population living in or around Kuala Lumpur in Malaysia were investigated and phylogenetic haplogroup lineages were determined. The intergenic COII/tRNALys 9-bp deletion, 3010 and 5178 mutations, and several coding region polymorphisms were examined to discriminate some phylogenetic haplogroups. Sequence comparison of the control regions led to the identification of 117 mitochondrial haplotypes, in which 103 types were observed in only one individual and the other nine types were shared by more than two individuals. Gene diversity was estimated to be 0.997. Phylogenetic haplogroup determination revealed that the gene pool of the modern Malay population in Malaysia consisted mainly of southeast Asian, east Asian, unidentified and unique, and aboriginal southeast-specific haplogroups. These results suggest a multi-original nature for the modern Malay population. The present database may help not only in personal identification but also in determining geographic origin in forensic casework in Malaysian, Southeast Asian and East Asian populations.
