Summary
The polymorphism of the major component of human complement (C′3 or \(\beta _{1^C }\)-globulin) at that time is interpreted formally by the genetic model “5 codominant alleles at one autosomal locus”. Examination of this hypothesis has been performed examinating a sample of 482 unrelated persons in the two populations, 71 families with 127 children and 115 mother/child combinations in a German population. It could be stated that 4 alleles or more are involved in this polymorphism.
