When are fingerprints formed, in terms of birth timing?

• A. At birth
• B. During adolescence
• C. In the utero before birth
• D. During adulthood

Answer: (C)

Fingerprints are created during fetal development in the womb, before birth. The friction ridges that make up their unique patterns form as the fetus grows, and the basic pattern is established by mid-gestation and remains essentially unchanged for life. After birth, the patterns don’t re-form; they simply grow with the fingers, with only local changes from injury. So the timing is in utero before birth, not at birth, in adolescence, or in adulthood.
