Are fingerprints the same for twins? That is, are they based on development, on the genetic code, or a combination of both? Its probably a dumb question, but it had me wondering.

The main cause of twins having different fingerprints is due to the individual development of each twin's fingerprints in the womb. Fingerprints are formed by the pressure and movements of the fingers against the amniotic sac, which is unique to each twin.
Yes, identical twins can have different fingerprints. While they share the same DNA, their fingerprints are formed through individual development in the womb, resulting in slight variations in the patterns.
Genetics do play a role in fingerprint development, as the patterns and ridges are determined by the genes passed down from parents. However, environmental factors and individual development in the womb also play a significant role in the final appearance of fingerprints.
No, fraternal twins do not have more similar fingerprints than non-twin siblings. While they may share some genetic similarities, their fingerprints are still formed through individual development and can have significant differences.
Yes, fingerprints can change over time for twins, just as they can for any individual. As we age, our fingerprints can become worn and altered due to factors such as manual labor or skin conditions. However, the underlying patterns and ridges will still remain unique to each individual.
