We analyzed the possibility of inherited predisposition to nondisjunction in a family with two cases of Down syndrome using restriction fragment length polymorphisms and cytogenetic heteromorphisms. In both patients the extra chromosome 21 was the result of a nondisjunction event at first meiotic di
