ABSTRACT

Data on the main-line index and R/L ratio in 2000 East- and West-Bank Jordanian subjects are presented and compared with those of other countries. In both males and females, the main-line index and R/L ratio in the East-Bank population were very close to those of the West-Bank population, which suggests that the two populations are not different genetically when dermatoglyphic features are considered. Both East- and West-Bank populations exhibited a relatively high main-line index as compared to other groups. A fairly marked degree of transversality of the general palmar configuration was indicated in the main-line index. The means of the main-line indices for males and their female counterparts showed no significant differences, but bimanual differences in both sexes were significant.

Keywords: Main-line index; Transversality.
