Your genetic makeup partly determines the whorls and ridges on your fingerprints.

Identical (monozygotic) twins come from a single embryo that divides early in development. They share almost (but not 100% due to mutations in utero) the same genetic information.

However, despite having almost identical DNA, monozygotic twins don’t have identical fingerprints.
