King stop looking at this as "Black African" genetics...you're going about this all wrong, there was Eurasian DNA in A. Egypt, you're going to have to deal with that and understand that the population history of every region, esp. Africa and a Cross Roads area such as the Nile Valley has a complicated Genetic history...

I hear you Jari, but autosomal was correct that 70%-94% matched with Black African regions. also dna that does not link with the color of Ancient Egyptians being Black is faulty at best

All humans are mixed and all populations throughout the Mediterranean have some level of mixture of some sort. This does not invalidate various populations in certain regions having a predominant phenotype, including skin color. Genetics does not invalidate the reality of human phenotype diversity and adaptability to certain environments. Africans are black because the continent straddles the equator and includes tropical and sub tropical environments. As such, if the ancient Nile Valley was populated from such areas, then of course they would have skin color matching that type of adaptation. Simple identification of maternal and paternal genetic lineages alone will not tell you about skin color genes.
quote: uman skin colour is highly heritable and externally visible with relevance in medical, forensic, and anthropological genetics. Although eye and hair colour can already be predicted with high accuracies from small sets of carefully selected DNA markers, knowledge about the genetic predictability of skin colour is limited. Here, we investigate the skin colour predictive value of 77 single-nucleotide polymorphisms (SNPs) from 37 genetic loci previously associated with human pigmentation using 2025 individuals from 31 global populations. We identified a minimal set of 36 highly informative skin colour predictive SNPs and developed a statistical prediction model capable of skin colour prediction on a global scale.

Skin coloration, however, is a more difficult physical appearance trait to examine genetically and to elucidate how its associated markers can be ranked for prediction, due to its population specific influence (Jablonski and Chaplin 2000, 2013). The maximal skin colour difference between people from different continents, as a result of environmental adaptation and consequence of the out of Africa migration (Liu et al. 2006), leads to a restriction in gene mapping studies. Genome-wide association studies (GWASs) are typically conducted in genetically homogeneous samples to avoid, as much as possible, the false positives that may be produced due to different genetic background between study samples. Therefore, GWASs on skin colour that are performed within continental groups such as Europeans (Han et al. 2008; Liu et al. 2015; Sulem et al. 2008) or South Asians (Edwards et al. 2010; Stokowski et al. 2007) basically identified a list of SNPs explaining subtle skin colour variation within each continental group, but in principle cannot reveal a complete list of skin colour-associated SNPs.

Doug is obsessed with skin color. He literally thinks all human beings can be classified as "white" or "black"
