esearch shows that the odds of a set of twins being conceived from two separate fathers is 1 in 13,000, and yet a paternity test has revealed that’s exactly what happened in one New Jersey family.
According to court documents, the mother, identified only as “T.M.,” gave birth to twin girls January 2013 and named a man, identified as “A.S.,” the father of both children when she applied for child support. But when she revealed she had sex with both A.S. and another man within a week of each other, social services requested a DNA test.
DNA expert Dr. Karl-Hanz Wurzinger testified that the test results delivered in November 2014 revealed there was a 99.9 percent chance that the two eggs were fertilized from two different fathers during the same menstrual cycle.
A 1997 study authored by Wurzinger suggests there’s a 1 in 13,000 chance of the incidence, based on reported paternity tests involving twins.
