The answer is no identical twins do not have identical fingerprints. Identical twins do have identical DNA, but fingerprints are shaped by more than just genes.

Fingerprints actually form before birth in the womb and are affected by factors such as the position of the foetus in the womb, nutrition, blood pressure and even how fast the fingers grow. Fingerprints are fully developed by the time a foetus is 6 months old, but can become more pronounced after birth.
