Remarks on some rare traits of finger and palmar dermatoglyphics

Rare dermatoglyphical patterns of fingers and palms of 26 different Hungarian population groups (males; 3207 individuals, 6414 hands) are compared with that observed in some population groups from the USSR (Buriats, Chookhchees, Kazakhs, Mansi and Komi), Khalkha-Mongolians, and Ethiopians (altogether 838 male individuals, 1676 hands). These patterns are: Radial loops on IV. and V. fingers, absence of triradius "d" on the palms, Ar,Lu and W + S on the hypothenar, Lc/Lr (Bettmann figure) and W + S on the thenar/I, and W on II., III. and IV. interdigital pads. It is pointed out that in addition to population studies these rare traits may also be used in genetic investigations (twin studies) as well as in forensic anthropology (disputed paternity).
