Fingerprints are epigenetic traits. Twins usually have very similar but not identical fingerprints. They can often be confused for each other, but generally they can be told apart on closer inspection.
Faces are really the only identifying feature of our bodies that’s genetic.
But why does our fingerprint grow back the same way when we damage our outer skin layer on our fingers? Or does it not?

If you damage your skin enough to remove the fingerprint, it doesn’t grow back. There are lots of people without fingerprints due to the types of work they do
