Phenotypic bioassay of five tribes of Orissa, India

From the phenotype distributions of six genetic markers, the mean coefficient of kinship in the five tribal populations of Orissa spanned over a rather small geographic area is estimated to be 2,613 x 10^-3 which is by any standard very low, signifying low affinity in spite of geographic proximity. However, at low level of clustering value the five populations seem to form two clusters of two populations each, the fifth one being mid way between the two clusters. These observations have to be supplemented by historic evidences since they are based only on six out of a vast spectrum of genetic markers which, possibly, can substantially characterize any population structure.
