title: Kinship coefficients and genetic distance among 23 Mexican Indian tribes.
abstract: Genetic distances (d) and kinship coefficients (f) of 23 Mexican Indian groups were obtained, based on the results of ABO, Rh, MN, Duffy and Diego blood group systems and serum haptoglobins. The results obtained did not correlate well with linguistic classification or geographical location and we conclude that the method used is not sensitive enough to correctly separate relatively similar groups which have different degrees of external admixture (with blacks and caucasians) and internal admixture (among themselves).
