In this classification, only whorl and loop pattern is considered on the right and left thumb. A white space must always intervene between the delta and the first ridge to be counted. When whorls appear in the thumbs the major division reflects the whorl tracings just as the secondary does, used Inner, Meeting & Outer or I, M, & O. ridge count is obtained by making an imaginary line between the delta and the core and then counting the number of ridges that intersect the line. Thus, FTS scores are computed individually for male (4030 samples) and female (4100 samples) of all the internal databases and shown in Table4.
