   What is Ridge counting in fingerprints?

   • In short: Ridge counting measures the ridges between the core and delta of a fingerprint. It is mainly used for loop patterns. Arches typically have a zero ridge count, as they lack a delta. Whorls often rely on ridge tracing, given their two distinct deltas. Why there is a Need for Ridge Counts in Fingerprints?

   Is finger ridge count a model trait?

   • Finger ridge count (an index of the size of the fingerprint pattern) has been used as a model trait for the study of human quantitative genetics for over 80 years. Here, we present the first genome-wide linkage scan for finger ridge count in a large sample of 2,114 offspring from 922 nuclear families.

   What is the difference between a ridge count and a whorl count?

   • Whorls have two triradii yielding two counts, while simple arches have no true triradii, resulting in a zero count. When the ridge count is used as a measure of a maximum pattern size on fingers, only the largest count from each finger is scored, and their sum is defined as the total ridge count.

   • The Identification Division of the FBI. The FBI Identification Division was established in 1924 when the records of the National Bureau of Criminal Investigation and the Leavenworth Penitentiary Bureau were consolidated in Washington, D.C.
   • Types of Patterns and Their Interpretation. Types of patterns. Fingerprints may be resolved into three large general groups of patterns, each group bearing the same general characteristics or family resemblance.
   • Questionable Patterns. No matter how definite fingerprint rules and pattern definitions are made, there will always be patterns concerning which there is doubt as to the classification they should be given.
   • The Classification Formula and Extensions. The classification formula. At this point it is necessary to mention that when prints are classified, markings are indicated at the bottom of each finger block to reflect the type.

    The total ridge count (TRC) was viewed as a common composite trait with definite correlations between its components — the ridge counts (RC) of individual fingers. The TRC variability was accordingly examined as a function of the variability of these components.
