Further studies on the genetics of the Chamorros of Guam: dermatoglyphics

The present study represents a continuation of our efforts to further define the genetic structure of the Chamorro population of Guam. The dermatoglyphic features of Guamanian Chamorros differ significantly from those of Western Carolinians from the Outer Islands of Yap in fingerprint patterns, model types of C line, frequency of patterns in the thenar/I area and in the presence of Sydney creases. The results of this analysis confirm earlier data from serological and other genetic markers that Guamanian Chamorros are genetically more closely related to the people of southeastern Asia than to their Micronesian neighbors to the south.
