Plato et al studied the digital and palmar patterns of 184 male and 224 normal American black, and 360 male and 360 female normal white children. Their findings revealed that white children had higher frequencies of whorls and radial loops and that black children had higher frequencies of arches and ulnar loops. As a result, the TFRC or whites was higher than in blacks. The pattern intensity index of whites was significantly higher than in blacks. (More triradii in fingers, palms, and feet.) The data presented show that black females with Gardner syndrome and their controls had higher frequencies of whorls than the respective white females. White males and females with Gardner syndrome had higher mean TFRCs than their respective controls. Unaffected and affected white males had higher mean TFRCs than black males in both categories. Black females with Gardner syndrome had higher mean TFRCs than their white counterparts.
