parentage testing

a test originally based on red cell antigens but increasingly on restriction fragment length polymorphisms (RFLPs), also called DNA fingerprinting. The offspring can have only those blood group antigens possessed by one or both of its parents. Identification of the offspring's antigens makes it possible to exclude some possible sires because they carry antigens not possessed by the subject animal. Similarly, the inheritance of a particular RFLP is directly linked to that found in each parent. Called also parentage determination, parentage exclusion testing.
