Around pregnancy and childbirth, there are many mysterious stories that are difficult to explain, such as a pair of twins with the same mother but different fathers. However, the stories below are even more surprising and strange when it comes to giving birth to children without being genetically biological.
“Hard to give birth” but she’s just my biological aunt
Lydia Fairchild is perhaps the most famous example of this situation. After divorcing her husband in 2002, Lydia applied for child support. At the same time, she is also pregnant with her third child.
Child support records required him to prove a mother-daughter relationship, so he submitted DNA samples of him and his children for DNA testing. However, the results surprised her, although her husband was genetically confirmed as the father of the children, the results proved that she was not the mother of her children.
Lydia is shocked to hear that her son didn’t carry his DNA with him.
It’s really unbelievable, because Lydia has pregnant and gave birth to my baby completely normal. For 9 months and 10 days, how much pain is born to be born, it is true, but DNA testing has always been considered the most accurate scientific basis for determining biological relationships. Even the baby lying on Lydia’s stomach, according to the test results, was not her “baby”, but her biological “niece”.
After the wife gave birth to a son, the husband took the test again to become the child of the “younger brother”
Liu (who lives in China) has been married for 10 years and has an 8-year-old son. His family is a normal family, happy when husband and wife love each other, work hard and have obedient children.
However, “turbulence” hit a year ago, when Master Luu took his son for a blood test. Who expects the result to make it into fire. His son’s blood type is AB while Mr. Luu and his wife have blood type O. Suspicious of the “problematic” results, he took the child to be tested again at another center but nothing happened.
The son does not carry Liu’s gene, but the “little brother” does not exist.
Therefore, he suspects that his wife is having an affair and that it was he who “broke the shell”. His wife insisted that he was faithful and since the day of the wedding, there had never been a “stealth”. In the end, the two decided to take their child to a DNA test to clarify the truth.
A week later, the DNA test results showed that the genome of Mr. Liu’s son did not match his, but the genome of his twin “brother”, which means that the child is biologically a human child, this “brother”. However, Mr. Luu does not understand because he is an only child and does not have twins.
Husband and wife perform in-vitro fertilization, giving birth to children with different blood types
According to Buzzfeed, an unnamed couple in Washington state (USA) gave birth to a son thanks to medical assistance in 2014. However, the two quickly discovered that the child’s blood type was completely different from that of the rest of the family, father and mother.
They questioned the center that performs in vitro fertilization (IVF), fearing the specialists might choose the wrong sperm, leading to the birth of another child. This clinic reviews the entire process and ensures there are no shortages during the IVF process.
The confused couple hired a lawyer and signed up for a DNA test at a reputable laboratory to confirm the results again. However, examination of the cheek skin cells of the 34-year-old husband concluded the same thing.

So they decided to follow the advice of geneticist Barry Starr of Stanford University. Starr experts recommend that fathers test ancestry via a device provided directly to the client. He explains that unlike standard paternity tests, which only look for 15 genetic markers based on a cheek swab, genetic inheritance tests look at hundreds of markers out of thousands. Sperm tests showed that the biological father was actually the baby’s uncle.
Chimera Syndrome
The answer to these three stories is Chimera syndrome. Chimera is an expression that comes from Greek mythology, which is the name of a monster whose body contains the parts of many different animals. In medicine, a chimera refers to a person who carries the gene pool of multiple individuals. This phenomenon is known as Chimerism, a genetic disorder in an organism.
Chimera is a genetic disorder that often occurs in twins.
In Lydia’s story, her genetic disorder is caused by “disappearing twin syndrome”. In other words, at first, Lydia belonged to a pair of twins, however, for some reason suddenly “reduced” to only one baby. At that time, one embryo no longer exists, but its cells are absorbed by the other embryo and the mother. The surviving embryo inserts the cells from the lost embryo into its own cells, and develops into a baby chimera.
And the two fathers in the following two stories are similar. They used to be twins in the womb, but then one fetus disappeared and their bodies “absorbed” the genetic sample from their brother. By the time they have a child, the baby inherits the genetic sample from the deceased “uncle,” not from the father.
