[QUOTE]Originally posted by Mike111: [QB] [b]Damn Mindless, I don't know what to say! I'm torn between disbelief and delight! I never thought that I would ever get you to explain what you were talking about, because I knew, that you knew, that once you did, then I would be able to tear into it. But you foolishly did it anyway, I just can't believe it! So let's begin the butt tearing! This is what you base your argument on:[/b] The distributions of the **derived and ancestral alleles** at TYR A192C, MATP C374G, and SLC24A5 A111G are consistent with the FST results suggesting strong European specific divergence at these loci. The *derived allele* at TYR, 192*A (previously linked with lighter pigmentation [Shriver et al. 2003]), has a frequency of 38% among European populations but a frequency of only 14% among non-Europeans.The differences between Europeans and non-Europeans for the MATP 374*G and SLC24A5 111*A alleles (both derived alleles associated with lighter pigmentation) were even more striking (MATP European 5 87%; MATP non-European 5 17%; SLC24A5 European 5 100%; SLC24A5 non-European 5 46%). [b]And you say:[/b] There are three alleles identified and are being discussed here, which are associated with the ancestral and derived state of darker and lighter pigmentations in Africans and Europeans respectively. The ancestral state being at TYR A192C, MATP C374G, and SLC24A5 A111G which predominates in sub-Saharan Africa and Island Melanesia, the derived state of these alleles on the other hand which are TYR, 192*A, MATP 374*G and SLC24A5 111*A, predominate in Europe, which is consistent with the FST results of the the distributions of both ancestral and derived, indicating that the derived version is strongly a European specific divergent at these loci and arose outside of Africa. So genius Mike, why don't these Africans carry the *derived alleles* at TYR, 192*A, MATP 374*G and SLC24A5 111*A alleles and instead carry the ancestral versions TYR A192C, MATP C374G, and SLC24A5 A111G predominately? How could this happen lil Mikey? [b]First some definations:[/b] Ancestor: one from whom a person is descended and who is usually more remote in the line of descent than a grandparent Ancestral: of, relating to, or inherited from an ancestor. Derived: being, possessing, or marked by a character - such as the large brain in humans (or Brown Skin in Albinos). not present in the ancestral form. FST = Fixation index Fixation index (FST) is a measure of population differentiation, genetic distance, based on genetic polymorphism data, such as single-nucleotide polymorphisms (SNPs) or microsatellites. It is a special case of F-statistics, the concept developed in the 1920s by Sewall Wright. F_{ST} = II{Between} - II{Within} II{Between} [b]To begin: You will recall that I earlier demonstrated that the Black European males and the INCOMING Albino females were doing THIS: (P.S. This is how Albino Mommy's and Black Daddy's make Brown Babies)! [IMG]http://realhistoryww.com/world_history/ancient/Misc/Med/Paestum/Naples_3.jpg[/IMG] In sexual reproduction each offspring gets half of its DNA from each of 2 parents, [/b][i]so each offspring is genetically different from both parents[/i][b] and usually from other offspring of the same parents. Thus the ancestral TYR A192C, MATP C374G, and SLC24A5 A111G (The Black African). When joined with ancestral TYR A192C*a, MATP C374G*a, and SLC24A5 A111G*a (The Asian Albino). Produces the "DERIVED" TYR 192*A, MATP 374*G and SLC24A5 111*A And since this joining of the Black African and the Asian Albino occurred in Europe, the "DERIVED" TYR 192*A, MATP 374*G and SLC24A5 111*A: CANNOT exist in either Africa OR Asia as it is "DERIVED" and unique to Europe ONLY. Graphic Demonstration of the DATA! [IMG]http://www.blackcelebkids.com/wp-content/uploads/2008/05/jamesbrownsonwife.jpg[/IMG] I can't believe you were dumb enough to do it![/b] [/QB][/QUOTE]
