Why do identical twins have different fingerprints?

It is true that identical twins form from one egg. They share some similarities when it comes to their DNA but fingerprints cannot be considered entirely as a genetic characteristic. This means that there are different factors that may affect the formation of any person’s fingerprints. The identical twins may develop their fingerprints while they are in their mother’s womb.

Their positions and movements may change the type of fingerprints that they will form. Some identical twins have very similar fingerprints but they are not exactly the same. The hormone levels of identical twins may also have an effect on the formation of fingerprints as well as moles and freckles.
