Dermatoglyphics of 100 male and 100 female phenotypically normal Black Americans living in New York City were analyzed. The significant bimanual asymmetry was noted only for patterns in the second and the third interdigital areas of the palms. The significant sex differences included excess of digital arch patterns in females and higher mean finger ridge counts in males. Distribution of dermatoglyphic characteristics of Black Americans in our study was compared to those of Black Americans studied by Steinberg et al. ('75) and Caucasian Americans studied by Schaumann and Alter ('76). The results show that significant differences in the dermatoglyphics exist not only between the Caucasian and Black subjects but also between the two groups of Black Americans.
