title: Blood polymorphism frequencies in the Tofinu, the "Water Men" of Southern Benin.
abstract: Informations on the genetic constitution (AcP, EsD, PGM1, AK, 6-PGD, Hb, Hp, Cp and Gc blood systems) of the Tofinu, a lacustrine population living in the pile-work of the Guinean coast (Southern Benin), are reported. The Tofinu gene frequencies are much as would be expected from the geographical position of this country. The AcP, Hp and Hb beta gene frequencies are compared with those of the other ethnic groups of Southern Benin as the Goun, Fon, Djedje, and Nago, using the contingency chi-square test of homogeneity. On the average, the five groups do not show any significant differences. Thus it results that there seems to be a common genetic origin and that the cultural-linguistic differentiation followed the evolutive biological process for the populations of this country.
