摘要：A total of 1, 530 blood samples from Japanese donors in Aomori and Fukushima were tested for their Dia and Din blood group antigens. The Dia gene frequencies obtained were: 0.044±0.006 in Aomori and 0.035±0.005 in Fukushima. These values are very close to those obtained by other investigators for southern Japanese (0.033-0.041: UEN0 and MURAKATA, 1957; TSUCHIYA et al., 1964; MISAWA et al., 1974; YAMAGUCHI et al., 1974).
