[QUOTE]Originally posted by xyyman: [QB] ^^Ish. Got that picture of Tarofalt? -- Quote: “Two derived allele variants in the SLC24A5 gene associated with predicting light-skin color in individuals with European and South Asian (Indian, Pakistani) ancestry are rs1426654 (derived state A, ancestral state G (94)) and rs16891982 (derived state G, ancestral state C (95)). Individuals with a[b] homozygous[/b] derived state for both these SNPs have been found in early Neolithic populations (Anatolia, Europe) (16)). [b]Our results show that these derived alleles are absent in the Taforalt individuals analyzed;[/b] all of them have a homozygous ancestral genotype for [b]both SNPs.[/b] The derived mutation for rs12913832 in the OCA2 gene is associated with blue eye color. A homozygous derived allele state at this position is the dominant determinant of light eye color in present-day Europeans and occurs at 100% frequency in Mesolithic hunter-gatherers (96, 97). Individuals with the ancestral allele A (homozygous or heterozygous) for this SNP show brown eye color 80% of the time (97). For [b]all the Taforalt individuals we find a homozygous ancestral genotype GG, predictive of brown eye color.[/b] In addition, all individuals show the ancestral GG genotype for SNP rs12896399 located in the [b]SLC24A4 gene, providing further support for dark eye pigmentation[/b] (93). The TCHH1 gene codes for trichohyalin, a protein active in hair follicle roots. For [b]all Taforalt individuals we find the derived homozygous AA genotype for SNP rs17646946 in this gene, which has been associated with straighter hair in Europeans[/b] (allelic effect (β) = 0.4-0.5, explained variance = 6.11%) (98). Xyyman comment: [i]Wow! Black skin, black hair, black eyes but straighter hair . Ish-Gebor posted that pictures of Taforalt. Europeans do not have ownership of straight hair. I said before straight hair may be ancestral to kinky hair. It may be a new phenomenon. But black skin made us humans. Even the Paleolithic Europeans were black. So we are back to Dravidian type peoples?[/i] [IMG]https://i.pinimg.com/originals/06/0e/cf/060ecfdca8d1cb5de2c05dd427585762.jpg[/IMG] [IMG]https://qzprod.files.wordpress.com/2018/02/xcheddar_man_for_web-pagespeed-ic-1mwojrtngm-2.jpg[/IMG] [/QB][/QUOTE]
