We studied human population structure using genotypes at 377 autosomal microsatellite loci in 1056 individuals from 52 populations. Within-population differences among individuals account for 93 to 95% of genetic variation; differences among major groups constitute only 3 to 5%. Nevertheless, without using prior information about the origins of individuals, we identified six main genetic clusters, five of which correspond to major geographic regions, and subclusters that often correspond to… 
Worldwide Human Relationships Inferred from Genome-Wide Patterns of Variation
TLDR
A pattern of ancestral allele frequency distributions that reflects variation in population dynamics among geographic regions is observed and is consistent with the hypothesis of a serial founder effect with a single origin in sub-Saharan Africa.
Population Genetic Principles and Human Populations
TLDR
Some recent advances in the detection of human genetic variation, the caveats and issues when studying genetic data from human populations, and the prospects of applying such information for identification of functional genetic variants in the human genome are reviewed.
Whole-Genome Patterns of Common DNA Variation in Three Human Populations
TLDR
This work has characterized whole-genome patterns of common human DNA variation by genotyping 1,586,383 single-nucleotide polymorphisms (SNPs) in 71 Americans of European, African, and Asian ancestry and indicates that these SNPs capture most common genetic variation as a result of linkage disequilibrium.
Genetic Variation and Recent Positive Selection in Worldwide Human Populations: Evidence from Nearly 1 Million SNPs
TLDR
Two genes involved in the thyroid hormone pathway that show signals of selection in African Pygmies that may be related to their short stature are identified.
Inter-chromosomal variation in the pattern of human population genetic structure
TLDR
This approach offers a comprehensive strategy for analysing chromosome-based population structure and differentiation, and demonstrates the application of complementary statistical and functional network analysis in human genetic variation studies.
Genetic Similarities Within and Between Human Populations
TLDR
This article demonstrates that classification methods achieve higher discriminatory power than ω because of their use of aggregate properties of populations, and provides empirical justification for caution when using population labels in biomedical settings, with broad implications for personalized medicine, pharmacogenetics, and the meaning of race.
Genome-wide SNP typing reveals signatures of population history.
Large-scale SNP analysis reveals clustered and continuous patterns of human genetic variation
TLDR
Analysis of 11,555 single nucleotide polymorphisms in 203 individuals from 12 diverse human populations provides a valuable resource for the definition of marker panels to detect and control for population stratification in population-based gene identification studies.
Genetic Variation and Population Structure in Native Americans
TLDR
Evidence is observed of a higher level of diversity and lower level of population structure in western South America compared to eastern South America, a relative lack of differentiation between Mesoamerican and Andean populations, and a partial agreement on a local scale between genetic similarity and the linguistic classification of populations.
A haplotype map of the human genome
TLDR
A public database of common variation in the human genome: more than one million single nucleotide polymorphisms for which accurate and complete genotypes have been obtained in 269 DNA samples from four populations, including ten 500-kilobase regions in which essentially all information about common DNA variation has been extracted.

High resolution of human evolutionary trees with polymorphic microsatellites
TLDR
It is shown that polymorphic microsatellites (primarily CA repeats) allow trees of human individuals to be constructed that reflect their geographic origin with remarkable accuracy by the analysis of a large number of loci for each individual, in spite of the small variations in allele frequencies existing between populations.
Patterns of human diversity, within and among continents, inferred from biallelic DNA polymorphisms.
TLDR
There is little evidence, if any, of a clear subdivision of humans into biologically defined groups at random biallelic loci, according to a range of statistical methods.
Genetic Differences Within and Between Populations of the Major Human Subgroups
TLDR
An analysis of all 15 pairwise comparisons among the geographic groups has shown the genetic divergence between major racial groups to be no more than a modest extension of the differences to be found between regions of the same group, accounting for only 51.6 ± 5.1% of the total between-population diversity.
An apportionment of human DNA diversity.
TLDR
By partitioning genetic variances at three hierarchical levels of population subdivision, it is found that differences between members of the same population account for 84.4% of the total, which is in excellent agreement with estimates based on allele frequencies of classic, protein polymorphisms.
Empirical evaluation of genetic clustering methods using multilocus genotypes from 20 chicken breeds.
TLDR
It is suggested that in species for which population structure is of interest, databases of multilocus genotypes at highly variable markers should be compiled and these genotypes could be used as training samples for genetic cluster analysis and to facilitate assignments of individuals of unknown origin to populations.
The distribution of human genetic diversity: a comparison of mitochondrial, autosomal, and Y-chromosome data.
TLDR
Analysis of worldwide genetic variation among 255 individuals by using autosomal, mitochondrial, and Y-chromosome polymorphisms reveals substantial congruity among this diverse array of genetic systems and offers broad support for an African origin of modern human populations.
Population structure, stepwise mutations, heterozygote deficiency and their implications in DNA forensics
TLDR
Applications of this theory to data on six Variable Number of Tandem Repeat loci and five short tandem repeat loci in the major cosmopolitan populations of the USA show that while the VNTR loci often exhibit a large significant heterozygote deficiency, the STR loci do not show a similar tendency.
The apportionment of dinucleotide repeat diversity in Native Americans and Europeans: a new approach to measuring gene identity reveals asymmetric patterns of divergence.
TLDR
The findings demonstrate that partitions of gene diversity into within- and between-populations components are heavily biased by the populations analyzed and the models fitted.
Race, ethnicity, and genomics: social classifications as proxies of biological heterogeneity.
TLDR
The burden of showing the scientific utility of racial and ethic identities in the construction and analysis of genomic resources falls on researchers, which requires that genetic researchers pay as much attention to the social constitution of human populations as presently is paid to their genetic composition.
Case-control studies of association in structured or admixed populations.
TLDR
This review article describes a series of approaches published over the past 2 years which use multilocus genotype data to enable valid case-control tests of association, even in the presence of population structure.
