Some researchers insisted that the ridges on the roof of the mouth contained patterns that were passed on from father to child. Others relied on the race-based pseudoscience of eugenics to create a list of physical traits like nose size, ear shape and hair texture that invariably passed from generation to generation. But the man who really captured the popular scientific imagination in the s was Dr. Albert Abrams and his oscillophore. Abrams had developed his own "scientific" theories about the human body's electrical system, which he called the "Electronic Reactions of Abrams" or ERA.
Convinced, like many others, that the key to unlocking heredity was in the blood, he invented a preposterous-looking instrument called an oscillophore that purported to measure the precise electronic vibrations in drops of blood: Irish blood vibrated at 15 ohms, Jewish blood at 7 ohms, etc. Despite the suspect and racialized science behind the oscillophore, Judge Thomas Graham of the Superior Court of San Francisco hired Abrams to determine the outcome of a high-profile paternity suit involving a man named Paul Vittori who refused to pay child support for an infant daughter he claimed was not his.
Abrams' magical machine found that Vittori was indeed the father and instantly made the eccentric doctor one of the most in-demand paternity "experts" in the world.
Paternity quacks like Abrams got so much traction, Milanich believes, because a frustrated legal system wanted a scientific panacea for solving the paternity problem.
Also, American society in the s was grappling with anxieties over rapidly changing gender roles and a new female sexual independence. These tests, as inaccurate as they actually were, offered the air of calm assurance.
But what's even more remarkable is what happened next. In the s, scientists discovered that human blood really did contain some definitive clues to a person's parentage. It wasn't electronic vibrations, but "blood grouping" — or what we know as blood typing : A, B, AB, O, etc.
Blood grouping follows some immutable rules. Finally, judges could use actual science to determine if a man could realistically be a child's father. But even science, it turns out, has limitations. In the early s, famed entertainer — and womanizer — Charlie Chaplin was taken to court in a paternity case brought by his former protege, Joan Berry.
Berry was 23 and Chaplin 54, and she alleged that he was the father of her newborn baby, Carol Ann. Accessed 14 Nov. More Definitions for paternity test.

Edited by Christina Swords, Ph. DNA inheritance Each one of us is born with a unique genetic blueprint. History of paternity testing Tests for paternity identification and family relationship linking have been used for more than years. Figure 1. Inheritance of blood groups. Each biological parent donates one of their two ABO alleles to their child.
Blood type A constitutes at least one copy of the A allele, but they could have two copies. The genotype is either AA or AO. The science behind DNA-based paternity testing The DNA fingerprinting technology first described in has now become a powerful tool for paternity and maternity testing. Methods for paternity testing DNA paternity testing involves collection of a DNA sample from a child and the potential father. Figure 2. DNA profiling in paternity testing.
Children inherit half their DNA from each parent and thus possess a combination of both. DNA fragments from the child should also be present in the fragments from the mother in grey and the father in black. Here, Father 2 is more likely to be the biological father. DNA sampling for paternity testing before birth While paternity testing can be easily carried out by collecting blood or cheek swabs from individuals, it is challenging if the test needs to be carried out before birth.
Amniocentesis This DNA collection method uses amniotic fluid that surrounds the fetus. Legal issues surrounding paternity testing Both legal and non-legal tests are available.
