title: Antigen sharing in couples in a two-locus ABO-like system.
abstract: The probabilities with which the two members of a couple share no, one or two antigens on each of two loci in ABO-like systems are derived. As an example, expected values concerning the HLA-A,B system are compared with observed frequencies in a material of 690 couples. A FORTRAN program for calculation of the gene-sharing probabilities is available.
