Inheritance of the Ag(x), Ag(y), (a₁) and Ag(z) Antigens

Abstract

Summary. The serum low‐density lipoprotein antigens Ag(a 1 ), Ag(x), Ag(z) were shown, by tests on 75 German families, to be inherited as autosomal dominants and to belong to one serum‐group system. Seventeen double back cross matings showed no recombinations in 31 possible situations, confirming that very closely linked loci, or a single genetic locus, are involved in their inheritance.
