Liu (a pseudonym)'s wife gave birth to a pair of twin sons in 2007, however, Liu found surprisingly that the second child has no blood relationship with him after a blood test. Liu decided to divorce with his wife a few days ago for he can't forgive his wife's betrayal. According to the medical experts, the probability of a pair of twins have two fathers is millionth.
According to Liu's lawyer that Liu's twins born by caesarean after the spring festival. The elder was nearly half a kilogramme heavier than the younger. In addition, the elder was stronger and higher than the younger one who often caught cold. Liu had more affection for the younger twin because of his weakness. Six months later, the second twin has been hospitalized because of fever. When Liu was take care of him, Liu focused on the boy's little face with a trace of doubt. The child didn't look like him and his blood type is A, but the child is O. Liu got suspicious and took the child for a paternity test. He was furious when he found out the child is not natural for him.
Liu thought that he is not the twins' natural parent so he argued with his wife, and she denied the betrayal. At the request of Liu, the four people did the paternity test. Again, the results of the identification puzzled Liu: the twins were all born by his wife but only the elder has blood relationship with the father. Thus, Liu's wife admitted that she had sex with her former boyfriend.
Liu Yuan was very upset about raise the child born by other. But if he got divorced with his wife, what about the custody of the child? So Liu came to consult a lawyer in Nanjing. And the reporter also consulted a lawyer about the problem. The lawyer said that the elder is Liu's natural child, and he can require the custody of the son. However, if Liu can prove that the second don't have blood relationship with him, he doesn't need to raise the child after the divorce.
The Reporter consulted the Director Tong Guorong of Reproductive Center of Maternal and Child Health Care Hospital, and he said that "twins of same mother but different father" might be happen according to reproductive principle. The twins should be the fraternal twins. There are Two types of twins, identical twins and fraternal twins, the former are formed from one fertilized egg split, and the latter has two eggs are fertilized at the same time. It is reported that the survival time of sperm is 72 hours, the eggs stored in the body is 48 hours. If a woman had a relationship with different man before and after ovulation within 72 hours while at the same time ovulate. She may have been fertilized with different sperm. Tong said it's the first time to hear the example of this for probability estimated as millionth. |
