title: [Apparently contradictory homozygosity of gc- and esd-markers in three generations (author's transl)].
abstract: In a paternity case we found contradictory blood group antigens in the serum- and enzyme-polymorphisms Gc and EsD of the child, her mother and grandparents. A possible accidental exchange of the child could be excluded by biostatistical calculations of the probabilities of motherhood, fatherhood and parenthood, and the descent from the parents was proven in both generations. The serological findings may be explained by the concurrent existence of silent genes or of genes that cannot be determined as yet. The genetic information Gc degrees descended from the grandfather and that for EsD degrees from the grandmother. Both were transmitted from the mother to the child. Thus, the case could be cleared by statistical considerations only.
