What is a distinctive feature of identical twins concerning fingerprints?

Identical twins, despite sharing the same genetic material, do not have identical fingerprints. Fingerprints are influenced by a combination of genetic and environmental factors, particularly during fetal development. While identical twins do possess very similar characteristics, the patterns, ridges, and minutiae of their fingerprints are unique to each individual.

This uniqueness arises because fingerprint formation is affected by random factors during development in the womb, such as the position of the fetus and varying pressure on the skin. As a result, even identical twins can have distinctly different fingerprints, allowing for individual identification.

The other options do not accurately reflect this established understanding of fingerprint uniqueness among identical twins.
