Dispermic origin of a 69,XXY triploid.
Triploidy, 69XXY, was found in a newborn with multiple abnormalities. Conception had occurred shortly after the mother ceased taking an oral contraceptive. The infant carried a pair of 21s with giant satellites; of the parents, only the father carried a giant-satellited 21. This, together with the XXY constitution, suggested a dispermic origin of the triploidy.
