Strait Herald, a Chinese newspaper, has reported on a Chinese woman and her birth of twins. The woman had an affair with another man, but in the end she could not hide it from her husband. No matter how much you hide and lie, the truth always comes out in the end. Sometimes the truth is found in unexpected ways. Every action has consequences, and this woman has learned that the hard way.
After the news was published, the couple went to the local police station to register the twins in the system. Xiaolong, her husband’s pseudonym, was shocked to discover that the twins were not identical. One of them didn’t look like her husband. Police requested a DNA test, and Xiaolong’s suspicions were confirmed. The twins had two fathers, DNA evidence showed.
Mr. Zhang, the director of the Fujian Zhengtai Forensic Identification Centre, expressed the anger of fathers when the results came back. The mother accused him of falsifying the results and confessed to having slept with the man. The father refused to raise the babies, not his daughter, according to a newspaper article. The couple now live in Xiamen.
This may seem impossible, but it is actually a rare phenomenon known as heteroternal superficiality. It happens when a woman has sexual intercourse with two men within a day or days of ovulation.
In some cases it can happen the day after the first egg is fertilized, but these cases are rare. If she ovulates before pregnancy, after sexual intercourse, the sperm can fertilize the egg. She may also become pregnant if she is pregnant by a first man. The two babies can develop at different rates.
Animals such as dogs, cats, cows and rodents are more likely to experience this phenomenon if they have more than one partner. Key factors include infidelity and promiscuity. A 1993 study showed that at least one in twelve identical twins (DZ twins) had maternity after a superficiality.
Another study claims that one in every four hundred twins in the US is born with two parents, and that 24% of paternity claims are caused by heteroparental or superficial fertilization, as reported in a 1992 study. This figure is thought to be much higher because most paternity claims have never been discovered, meaning many people do not need legal advice.
