Multiple-locus allocation of individuals to groups as a function of the genetic variation within and differences among human populations
- Univ. of Michigan, Ann Arbor
Multivariate (multiple-locus) analytic procedures are used to show that the amount of genetic overlap of two or more populations, as measured by the difficulty of correctly allocating individuals, may be formally related to the average genetic distance between pairs of populations. On theoretical grounds, it is argued that the probability of correct allocation for individuals should: 1)increase with the number of segregating loci; 2)increase with increasing taxonomic disparity of the populations considered; and 3)decrease with an increase in the number of candidate populations. Genetic data on 5,214 individuals from seven South American Indian tribes are used to evaluate these theoretical predictions, and the genetic distance and classification with the seven tribes is analyzed.
