[Rugen (Germany): hemogenetic study of an island population]

24 haemogenetic markers (5 erythrocyte antigens, 7 polymorphisms of serum proteins. 12 polymorphisms of red cell enzymes) had been studied in up to 171 individuals from the island of Rügen (Germany, Baltic Sea). The cluster analysis separates clearly the ügen sample just as the islands of Hiddensee and Ummanz from the neighbouring populations. The comparison of the data with neighboured larger populations as for instance Denmark, Hamburg or Sweden clearly results in an exceptional position of the island of Rügen. The possible reasons are discussed.
