Born but still not your father - one of the most bizarre phenomena in the world

Born a child, but when he tested DNA, dozen firefighters found out that he was just his uncle. What's going on? Perhaps the wife had given him a horny husband?

In fact, the phenomenon of a person who even gives birth to a child but is not the father of a child who happens to be extremely rare, is called the Chimerism - or Chimera gene.

The story of an infertile family and a rare lawsuit in Washington.

In June 2014, a couple in Washington relied on technology to treat infertility, and then a child was born.

But during a blood test, the results made the couple extremely surprised, the child was not the son of the husband. DNA test results also show that two people only share 10% of the genetic code.

The family decided to sue the hospital because they thought they had a mistake when sampling sperm. But after the examination, the hospital confirmed that there were no errors, at the time, he was the only white person to send sperm samples to the hospital and the white-colored child.

The couple asked the Stanford University geneticist Barry Starr. After performing hereditary genetic tests, Starr's conclusions made everyone surprised: the man with the relationship . the uncle.

Starr said, if you are father and son, there will be 50% of DNA related to each other, when it is only 25%, it is my uncle's relationship. In this case, the correlation between both is 25%.

Chimerism - gene disorder phenomenon in a body.

The above case is an extremely rare phenomenon and is scientifically identified as "Chimera", to refer to genes assembled from many individuals.

Chimera gene appeared during double conception, then two embryos will have different genetic structure. But because of one reason the two embryos are combined into one in the early period, or a degenerate embryo should be absorbed by the remaining embryo.

But not all of the genetic structure will be assimilated, some cells will lurk inside the remaining fetus without being eliminated. Therefore, the born child will have two genetic structures, one of the surviving embryo, one of the twin embryos.

The case of the above husband is the clearest evidence of genetic disorder in a body. The husband carries the genetic structure of himself and his twin. And because DNA samples in his sperm have up to 90% of his twin's DNA, it makes things complicated.

Professor Starr also commented, it seems that not only the sperm sample of the husband is mixed with the brother but also the skin cells are synchronized, as proof that his skin has lines sync, place bold spots. Other cells and organs are also likely to be mixed.

Similarly, the Chimera phenomenon also occurs in women and causes the mother to give birth to a child but not the mother. Lydia Fairchild is such a case, she was once deprived of custody because the DNA results do not match. It was only after Fairchild was identified as a Chimera that everything became clear.

Lydia Fairchild - a very famous case of the Chimera gene.

According to Dr. Dieter Egli from Columbia University, Chimerism not only appears in double conception cases but also in cases of organ transplants, and in stem cell experiments he himself is carrying out. . He said that now people are starting to use cell transplantation technology in treatment so we need to find out if the Chimerism phenomenon affects people, how they perceive their identity. .

Chimera has also been recorded in animals. The most famous is the Quimera cat from Argentina, with her face divided into two halves, each with a different color of hair and eyes.
