[QUOTE]Originally posted by xyyman: [QB] Whenever you are up to it. All that you mention below sounds impressive. I simplified it for others. At least I thought I did. I say light blue component is North African and not Southern European. Educate us. I don't understand. I have never run 100s of test. I repeat. For the record read the supplements: Pg 16 Supplementary Note 4: Details of Structure-like Patterns Old World Analysis (Entire Sample Set) Dark Brown San/Pigmy Light Brown Bantu Dark Blue European (north and south) Dark Purple Mazabite unique. Light Purple Arabian/Ethiopian Light Blue- North African Light green Middle Eastern Dark Green Middle Eastern The author does not classify light blue as European(south) because he cannot. Why? [QUOTE]Originally posted by beyoku: [qb] [QUOTE]Originally posted by xyyman: [qb] @ Beyoku to clarify. I interchangeable use dark purple and purple. I did not include light purple in my analysis. Looking at the Pakistani group is a clear indication that light blue is North African and not Southern European. Because the SSA components proportionally shows up in these Pakistani groups. The same pattern is seen with ALL the Jewish groups globally. Including Yemeni and Indian/Pakistani. Ie African (SSA and Saharan) SNPs as a proportional block at all k-clusters [/qb][/QUOTE]Sigh....I dont even know where to start. You are going to have to be familiar with the STRUCTURE and ADMIXTURE applications to know what is going on. You are not familiar with these applications that is why you are making mistakes interpreting the data. You are going to have to see other ADMIXTURE runs where they use some of this same data. Mozabite are somewhat inbred BUT when right along with other North African groups they are not inbred to the first cousin level to create their own artificial cluster. THe Mozabite were usually on par with Maghreb ancestry as southern Moroccans and Saharawi - This is data that has been proven PRIOR to the introduction of the Tunisian data set. Purple does not show up at K=9. It shows up at K=10 and peaks in the Mozabite. The "Light Purple" component that materializes at K=9 is more descriptive of some kind of South WEST Asian ancestry...It peaks in Yemenis, Saudis and Ethiopians. Getting into the details. If you want to say that the purple is NOT Maghreb and is something else.....then Mozabite and Moroccans have VERY LITTLE NORTHWEST AFRICAN ANCESTRY! Moroccan JEWS have more North West African ancestry than Moroccans! Romainians and Hungarians have MORE North West African ancestry than the North West Africans in the study. :eek: This makes no sense.....If that light blue you see peaking at K=10 in Sardinia = Maghreb ancestry then most of the people carrying that Ancestry are more BERBER than the BERBERS in the study. Can you understand this? In this program, once a new K is materialized, everything gets shuffled around. I am fimiliar enough with the program and its uses to have seen the Mozabite and other North Africans in these exercises probably HUNDREDS of times. I have analyzed me OWN ancestry using these programs. @Troll Patrol - Southern Arabians are Southern Arabian. There are populations in Arabia that are African. Some recent, some ancient. From an OOA perspective the aboriginal population of Arabia which I assume would be the continuation of IJ* lineages and RO/N lineage are not "Africans". SOme of them may look like Africans but they are not Africans. The people on Socotra may look like Africans but they are not. Very little L lineages are found there....and Only 10% E - Lowest in all of Arabia. [/qb][/QUOTE] [/QB][/QUOTE]
