Possibility of Babies having Two Biological Fathers- Fascinating
A recent research by Lisa Landry, a medical editing/transcription at Independent Contractors wrote on Jan. 11 that, chimerism is the only way this could happen biologically. I strongly attest to this factor on this interesting topic.
Chimerism is a trait whereby a single organism is made up of cells from two or more individuals; which literally implies that, the organism contains two sets of DNA, possessing blood cells of different types and a subtle variation in form. Chimerism is also another factor which leads to hermaphroditism (the possession of both male and female organs). Chimerism naturally occurs in humans when a fetus absorbs its twin. This is mostly to occur with fraternal twins- if one embryo dies at the early stage of the pregnancy and some of its cells are “absorbed” by the other twin. The surviving fetus will then have two sets of cells which is, its original set in addition to the one from its twin. It’s very sad individuals who grow up with this form of chimerism are always ignorant about this fact. Another natural chimerism that occurs in humans is the tetragametic chimerism which occurs when two different sperm cells fertilize two different egg cells. These cells fuse together into one human embryo.

The only artificial way chimerism occurs is when he or she undergoes a bone marrow transplant. Bone marrow transplant is a treatment given to leukemia patients. Bone marrow contains stem cells that develop into the red blood cells. In some strong cases, all the blood cells in the person who received the bone marrow transplant matches the DNA of his or her donor. The person is then referred to as a chimera.
Some traits of Chimerism in humans
- Hermaphroditism: which I have made mentioned already in this article.
- Different in colors of the eye pupil as seen in the image below.
- Hyperpigmentation(increased skin darkness) and hypopigmentation ( increased skin lightness) in patches or across areas as large half of the body.
