[QUOTE]Originally posted by Amun-Ra The Ultimate: [QB] [QUOTE]Originally posted by Swenet: [qb] [QUOTE] Originally posted by Amun-Ra The Ultimate: and blowing some air.[/QUOTE]Yeah, like equating a SNP with a STR, or referring to Ks as ''populations''. [QUOTE]For a guy who says sampling got no impact of the raw results[/QUOTE]My reference to the low impact of sampling was obviously meant as in sampling more populations than they already have. But taking stuff horribly out of context is what you're known for here on ES. [QUOTE](Ks are indeed "postulated ancestral populations" btw).[/QUOTE]You have absolutely no idea what you're talking about. Its literally oozing from everything you say. And I'm not just talking this thread. [QUOTE]that's why it's surprising to see the study make reference to them (for example, saying "North African populations are distinct from sub-Saharan Africans").[/QUOTE]And that they're referring to the under-sampled Saharan proper populations when they say that, is evidenced by what? [QUOTE]For example, [b]it's possible that some Berber (or other coastal North African groups) share more affinities (SNP alleles values) with black Africans groups close to them geographically[/b] but much less with Nigerians or Kenyans.[/QUOTE]You're too much of an ignoramus to have noticed that both the Fulani, Hausa and Bulala samples qualify for what you're stating above. The very populations you go at lengths to say weren't sampled, are actually sampled, as I've tried to point out earlier (but, to no avail). [QUOTE]share more affinities [b](SNP alleles values)[/b][/QUOTE]LMAO at ''SNP alleles values'', when the 'S' in SNP means SINGLE. Does ''single'' strike you as compatible with value[b]s[/b]? You're a walking caricature, not to be taken serious, not even by the Euronut trolls. [QUOTE]Also the North African population include indigenous black African population [b](usually in the south of those countries)[/b][/QUOTE]Again, you simply don't understand what you're discussing. The Fulani, Hausa and Bulala already qualify for what you're stating above. [/qb][/QUOTE]You say I'm wrong but you give no explanation why. We suppose to believe you without explanations? Let's exchange information not hot air. 1) Nigerian and Kenyan populations are not the same than black African in North Africa. They have different SNP DNA values. They are more likely to have interacted other people in North Africa since they are geographically closer and are more likely to share DNA with them (among other thing). 2)Even if SNPs are *single* nucleotide polymorphism they still have different alleles values that's why we're making the study. The values correspond to the different nucleotides it could have (A, T, C or G). Obviously, there must be at least 2 different alleles values in a population to be considered an SNP. At a single site on the DNA strand people (a population) can have many different allele values depending on their ancestry (or mutation). In fact each person can even have 2 values at the same site (one in each chromosome passed from the mother and the father). This is from Wiki: [i]For example, two sequenced DNA fragments from different individuals, AAGCCTA to AAGCTTA, contain a difference in a single nucleotide. [b]In this case we say that there are two alleles.[/b] [/i] That's pretty basic, it's funny you don't understand that. You're the one making a fool out of yourself you will pardon me to say. 3) If you don't consider Ks "postulated ancestral populations" then I want to know what do you consider the Ks are?
