Just how identical are identical twins? If you’ve ever spent time around identical or monozygotic twins you have probably been wowed on how alike they are in more than just looks and the connection they have together. One question that many have thought about in regards to identical twins is do they have identical fingerprints? Now this question may not be of high importance the to parents of identical twins, but for others it tinkles their curiosity. Considering the fact that identical twins develop from the same egg that splits at conception., many might think that twins would have the same prints.

Now facts that we know is that identical twins have identical genetic DNA, and it is virtuously impossible to distinguish the twins apart. What many people are not aware of is that fingerprints are not entirely genetic. Fingerprints along with a few other characteristics are a combination of things, or also known as a phenotype. A phenotype is when an individuals genes and environmental aspects are apart of development. This is similar to the nature vs. nurture theory. Scientist believe that fingerprints are formed by a combination of environmental factors during pregnancy such as nutrition, blood pressure, position in the womb, and the growth rate of fingers.
