Yes, it is possible for two people to have similar fingerprints, although the likelihood of two people having identical fingerprints is extremely low. Fingerprints are unique to each individual and are formed by the arrangement of ridges, valleys, and patterns on the skin of the fingertips. While there is some variability in the patterns, the overall ridge arrangement is unique to each person. The probability of two people having the same fingerprint is estimated to be around 1 in 64 billion. It is important to note that while it is highly unlikely for two people to have identical fingerprints, it is possible for two people to have similar enough fingerprints that they can cause confusion or difficulty in fingerprint-based identification systems. This is why fingerprint analysis typically involves a combination of features, including ridge count, ridge pattern, and ridge characteristics, to determine a positive match.
