What is a human chimera?
- When the human body absorbs the DNA of an unborn twin
Yeah, it's as creepy as it sounds and it is said that it actually happens in 1 in 8 pregnancies. Sometimes, in the womb, two or more fetuses begin to form, when only one develops, it takes on the DNA of a "ghost twin". It is usually not a big deal and it goes completely undetected in most people, that is until you take a paternity test and you fail because the DNA in your sperm doesn't match the DNA in your saliva making you the father and the uncle of your own child. Yep, that actually happened.
