Guizhou, 87.5% Miao in Guizhou, 84.0% Dai in Luxi, Yunnan) and from neighboring Laos (97.0% Laotian) and Thailand (89.9% Thai). However, Gm afb1b3 is almost equally common among people in Malaysia (97.3% Kadazan on Borneo, 85.0% Malay), Indonesia (76.6% Sulawesi, 75.2% Java), the Philippines (83.6% Luzon Filipinos, 76.4% Luzon Negritos, 67.2% Mindanao Negritos), Karen people in Thailand (82.3%), Kacharis in Assam (80.9%), Cambodians (76.7%), Taiwanese aborigines (76.2%), Micronesians (88.7%), Melanesians (74.6%), and Polynesians (74.7% Cook Islands, 69.4% Hawaii). The study found that the mean frequency of Gm afb1b3 was 10.6% (range 7.8% Shizunai to 13.0% Osaka) for the general Japanese population. Minimum frequencies (4.0% to 4.4%) of Gm afb1b3 were found among the native people in the Yaeyama and Miyako islands in the extreme south of Japan and among the Ainu (4.3%) in the extreme north of Japan. The author suggested that the somewhat elevated frequency of the Gm afb1b3 gene among the mainstream Japanese compared to the Sakishima islanders and the Ainu may have resulted from some admixture of the mainstream Japanese population at rates as low as 7–8% with southern Asian (from southern China or Southeast Asia as far west as Bangladesh and Nepal) populations having the Gm afb1b3 gene in high frequency.
