discovered polymorphisms. These data will further amplify the forces of genetic ' 
drift, migration, and possible selective forces acting on these isolated island 
populations suspected of having as high a coefficient of kinship as can be found 
an3where in the world. 
IV. Dermatoglyphics 
Fifteen hundred subjects were palm and finger-printed on both hands for 
dermatoglyphic analyses by Dr. Chris Plato of the National Institute of Dental 
Research at the National Institutes of Health. The data will be sued to search | 
for phenotypic differences in palm printing pattern and finger print pattern 
distributions, and in ridge counting, in order to find evidence for ji 
relationships or genetic distinctions among the various island poulations jj 
studied. An attempt is also being made to use dermatoglyphic data in genetic 
distance studies, employing erythrocyte antigens, serum protein, and red cell | 
enzyme pleomorphisms , for the study of genetic heterogeneity and gene drift by |i 
genetic distance techniques. * 
V. Genetic Distance Studies Between Island Groups I 
Information on close to thirty polymorphic loci, as well as dermatoglyphic 
phenotypes and kinship patterns, will be used in genetic distance analyses of 
the island populations surveyed. Genetic heterogeneity, as well as coefficients 
of kinship, will be determined. Graphic analyses, including the construction of 
genetic networks and principal components analysis, will also be attempted. 
Distinctions between kinship, determined by bioassay (from polymorphism data) 
and that determined by migration patterns, dermatoglyphics, and kinship patterns 
obtained from history, will be contrasted.
