Abstract
A total of fourteen hundred individuals of two local populations living in Toshi-jima Island, Mie Prefecture, have been investigated for genetic variations in blood groups, two serum proteins and twelve red cell enzyme systems, namely, ABO; Hp, Tf; AcP, PGM, GPT, PGD, EsD, ADA, PHI, GOT, LDH, PGK, AK and PepA.
The results showed a remarkable difference between two populations. Also comparisons were made with the results obtained for the neighbouring populations in Kamishima (Toyomasu et al, 1977) and mainland of Mie Prefecture.
