| Research Abstract |
This study revealed the followings :(i) The Ryukyu islanders were genetically closer to Honshu Japanese than Taiwan aborigine, and(ii) showed a strong relation with Hokkaido Ainu.(iii) Shovel shape of upper incisors, a common characteristic in East Asians, showed an association with a variant in EDAR gene.(iv) The mtDNA tree of the Japanese medaka showed the northern Kyushu origin that might be related to the expansion of wet rice cultivation.(v) The pattern of SNP frequencies of the genes related to alcohol metabolism was consistent with the dual structure model.
