Can twins have the same fingerprint?

Published in Biometrics 1 min read

No, even identical twins, who share the same DNA, do not have identical fingerprints. While their fingerprints might appear similar at first glance, subtle differences arise due to environmental factors experienced in the womb. These factors influence the development of fingerprints during fetal development, resulting in unique patterns for each twin.

Identical twins have a high degree of similarity in their fingerprint types, but their individual patterns are still distinct. This is why fingerprints are a reliable form of identification, even for twins.
