A. W. F. Edwards (2003) argued that analyses that consider only locus-by-locus variation can be misleading because they ignore correlation structure among multiple genetic loci, and that correlated allele-frequency patterns across loci can contain information enabling stable population classification.

Conceptual critique emphasizing multivariate structure ('correlations among loci') as a source of classificatory information.
A 1972 analysis by R. C. Lewontin of 17 polymorphic loci across seven population groups reported that on average 85.4% of human genetic diversity is contained within populations, 8.3% among populations within races, and approximately 6.3% is attributable to racial classification.

Lewontin's 1972 partitioning of genetic variance by locus-by-locus analysis across defined 'races'.
In 1972, geneticist Richard Lewontin published a study analyzing protein-type variation across human populations and reported that about 85% of genetic variation occurred within populations and 'races' and about 15% of variation occurred between them.

Lewontin's 1972 partitioning of genetic variation is widely cited in discussions about the biological basis of race.
