Fig 1.
The three basic fingerprint patterns: from left to right- Loop, Whorl, and Arch fingerprint pattern types.
Ridge counts are determined by drawing lines that connect the core/centre of the patterns with the respective delta (triradius), thus yielding two ridge counts for the whorls, one for the loops, and none for the arches (since they lack a delta).

Neighbour Joining Tree for the studied groups.
The relative similarity between the studied groups inferred from the inheritance model of Slatis [16] & pattern frequencies. The two Semitic groups (Amhara, Tigray) have clustered out together, as have the Cushitic (Oromo) group that fall under a broader cluster of the Afro-Asiatics. The Nilo-Saharan Berta group, being from a different linguistic family, has clustered out separately.
