Do Identical Twins Have the Same Fingerprints and DNA
This is an interesting question. So what do you think? Well the answer is “No”. Just because you look the same does not mean your fingerprints will be the same. Everyone has his or her own fingerprint. However, because twins are from the same egg just split in two they will have the same makeup or DNA. This is actually referred to as a monozygotic- rising from one egg. Fingerprints are thought to be shaped from environmental factors. These things are nutrition, blood pressure, womb positioning and the growth rate of the fingers. Certain ridges and patterns could be the same but there are also differences. Everyone on this planet is different even if they look the same. They are still an individual.
In the case of fingerprints, the genes determine the patterns used for classification. As the skin on the fingertip evolves, it expresses these characteristics. It is also in contact with the amniotic fluid in the uterus. It is also in contact with other parts and responds to the movements of the mother. The microenvironment of the cells on the fingers is constantly in movement. This movement determines the patterns on the fingers to be ever so slightly different. This is the same concept that makes each winter snowflake unique and special. I am sure your parents probably told you that one winter. Also as twin’s age, their DNA changes and they move farther apart and more individual in chemistry.
I came across a question while I was researching this piece, which is very interesting. Why do we have fingerprints? A fingerprint expert name James Cowger thinks he knows. His answer is fingerprints help us grasp things. He calls them “friction ridges”. He thinks we would all be lost without them and would be constantly dropping items. If that is the case, I must not have any fingerprints. I am constantly dropping items especially glasses and kitchen utensils which my husband does not understand? It is a mystery. Speaking of mysteries, DNA and fingerprinting are used to solve many crimes. DNA is taken from body fluids or fragments. DNA stays the same throughout life so they are a good way to find criminals.
So now, when you see twins you will know that although they may look the same their fingerprints are different. They are actually individuals with the same DNA.
