How are fingerprint patterns classified after being categorized into three general types?

Fingerprint patterns are classified into three general types: loops, whorls, and arches. Once categorized into these general types, they can further be classified into smaller sub-groups based on specific characteristics and unique features within each main category.

For example, within loops, there can be variations such as radial loops and ulnar loops. Whorls also have sub-classifications, including plain whorls and central pocket loops. This granularity allows forensic analysts to differentiate fingerprints more effectively, enhancing the accuracy of identifications and comparisons.

This process of breaking down general types into more detailed classifications is essential in forensic science, as it provides a more precise way to analyze and match fingerprints, which is crucial for solving criminal cases.
