Restriction and persistence of polymorphisms of HLA and other blood genetic traits in the Parakanã Indians of Brazil.

abstract：:Heterogeneity and small sample size are problems that affect many paleodemographic studies. The former can cause the overall distribution of age at death to be an amalgam that does not accurately reflect the distributions of any of the groups composing the heterogeneous population. The latter can make it difficult to ...
