Lewontin found 85% human genetic diversity within populations using classical markers. Those same markers enabled early forensic identification. Modern STR profiles yield RMPs of 10^-26 for individual ID. Forensic STRs show low global FST of 4.5% underestimating inter-population variation. CODIS loci cluster populations like Europeans Africans East Asians. AIM SNPs like Duffy show 90%+ negative allele in sub-Saharan Africans rare elsewhere due to malaria selection. Skin color variation is 9% within populations mostly between due to selection. Hair eye color variation mostly among Europeans. Forensic BGA panels cluster into 8 ancestry groups resembling genome-wide patterns. Pigmentation SNPs predict EVCs but fail in admixed populations. Ancestry markers entangle with pigmentation reinforcing racial categories. Duffy EDAR variants mark African Asian ancestries phenotypically. Forensic methods highlight non-neutral markers maximizing group divergence. Lewontin's within-group dominance ignored in ancestry phenotype prediction. BGA EVCs narrow suspects to ethnic pools risking community targeting. Universal databases proposed to avoid biased ancestry inferences.
