Hemogenetic studies in southern Germany

Typing of 23 blood groups, serum protein and red cell enzyme polymorphism was performed on two samples from Baden-Württemberg, Germany. One random sample comes from the city of Ulm and its surroundings and the other from a small isolate located in Upper Swabia. While the Ulm sample displayed allele and haplotype frequencies similar to those of other German populations, the sample from the isolate turned out to be different.
