Do we often witness and see such kind of image on the internet and asked ourselves how does it happen and what could be the reason behind it? Well! We will explain the reason behind it.

Genetic chimera is a phenomenon where an organism or tissue contains minimum two different sets of DNA. The name chimera comes from the Greek mythology which is a combination of lion, goat and dragon. In human chimera occurs when a woman is being pregnant with fraternal twins and one embryo absorbed its twin cell. Though it can also occur after bone marrow transplantation in time of normal pregnancy but it happens on very small scale compared to the first one. It could be happened by another incident known as micro-chimera from pregnancy. It happens when cells are exchanging between a woman and fetus. Though most of the cells die off but a few may stick around and transfer it’s baby’s DNA. Experts are confused about how many chimeras exist in the world because the condition is believed to be quite rare.
