DNA is the genetic materials that we all carry in each of our cells. It contains the information that made us who we are. The combination of the DNA of both of our parents resulted in the DNA that is unique to us. This is the reason why DNA testing is prominent in many identities testing. Normally when you do a DNA test it will show how you are related to either your parents or child. But do you know that there is a rare group of humans who does not share the same genetic information with their child? These humans have two different sets of DNA, which is expressed in different parts of their body. For a mother, this means that the DNA in her blood is different than the DNA that she carries in her egg. Thus, resulting in a child that does not share the same DNA as the DNA in her mother’s blood. This condition is known as chimeras. Human chimera has two different sets of DNA that they gained while they’re still in embryo stage. It usually happens when a mother is pregnant with fraternal twins and one of the embryos died. The still alive embryo will then absorb the remaining cells from the dead embryos resulting in two different sets of DNA existing in one embryo.
