The orientation of finger pads in the womb plays a significant role in determining unique fingerprint characteristics. As the fetus develops, the pressure and position of the finger pads interact with the surrounding amniotic fluid and the environment within the womb, leading to the formation of ridges and patterns on the fingertips. These ridges are unique to each individual and are established during fetal development, making fingerprints a reliable means of personal identification.

While other factors like friction and wear can influence the appearance of fingerprints after birth, the foundational characteristics are set before a person is born. This uniqueness is why fingerprints are widely used in forensic science and personal identification systems.

In contrast, aspects such as fingerprint smudging, potential for calluses, and finger sensitivity are influenced more by external factors and bodily changes that occur after birth, rather than the intrinsic characteristics determined in the womb. The uniqueness and permanence of the fingerprint patterns are fundamentally linked to the prenatal development conditions, which makes the characteristics of the fingerprints unique to each individual.
