Paternity Fraud

"Researchers conducting a study into inheritance of blood groups in America in the mid 1900’s discovered that 1 in 10 babies blood types could not be explained by hereditary factors alone. The results of this research were kept secret for many years.

“In the early 1970s, a schoolteacher in southern England assigned a class science project in which his students were to find out the blood types of their parents. The students were then to use this information to deduce their own blood types (because a gene from each parent determines your blood type, in most instances only a certain number of combinations are possible). Instead, 30 per cent of the students discovered their dads were not their biologically fathers.

"The classroom was, of course, not the ideal place to find out this information," said Prof. Dickens, who is often consulted on ethical issues by geneticists at the Hospital for Sick Children”

A study published in the Journal of the American Medical Association in 1995, “Blood Grouping Tests in Undisputed Paternity Proceedings”, using the A-B-O blood typing system, it was found that 18% of the men who had voluntarily admitted paternity, were not the actual fathers of the children.

The use of blood groups for testing for paternity is not very accurate, as O and A blood groups are the most common."

"Data from the American Blood Banks Association shows assumed fathers requesting the use of DNA that 30% are found not to be the child's biological father and this is just from males who have a doubts about whether they are a child's father or not.

A research paper Prenatal paternity testing with deoxyribonucleic acid techniques published in the American Journal of Obstetrics and Gynecology in 1996 found in postnatal testing 37% of alleged fathers were excluded from being the father of that child. Prenatal testing excluded 53% of alleged fathers. 753 postnatal paternity tests were performed and in the study each mother admitted that the paternity of her baby was ambiguous."
