[QUOTE]Originally posted by Doctoris Scientia: [QB] [QUOTE]Originally posted by zarahan: [qb] [QUOTE]Originally posted by Doctoris Scientia: [qb] ^ Shut up, no ones grouping Ethiopians in the Caucasian race... LOL And J1 is likely African, since Ethiopian J1 dosen't match any known population outide the Sudan... and the highest frequencies of J* are in places like Socotra and Hadhramaut Yemen. Socotra http://www.flickr.com/photos/25039035@N03/4548979467/ Hadhramaut http://www.flickr.com/photos/kellyphotos/sets/72157603913412055/ The fact that Ethiopian J1-M267 dosen't match those found in Yemen or Saudi Arabia debunks admixture. Only 2% of the J1 found in Ethiopia is of recent or historic admixture. J1* most likely originated along the African Red Sea coast, it would then expand from places surrounding Socotra... people carrying E3b and other lineages would decrease the freguency of J1*, J*, and J1-M267 among people living in Ethiopia and Sudan. Socotra being isolated, continues to have a high freguency of Haplogroup J. [/qb][/QUOTE]Interesting. Do you have a scholarly reference that shows what you say about the uniqueness of J1-M267? [/qb][/QUOTE]Yeah, here some... also I posted some information on one of your threads on Egypt Search Reloaded. "Haplogroup J, characterized by the mutation 12f2.1,has been found at a frequency of approximately 18% in Ethiopians, with a relatively higher prevalence among the Amhara, where it has been found to exist at levels as high as 35% , of which about 33% is of the type J-M267, almost all of which was acquired during Neolithic times or earlier, while 2% is of the derived J-M172 type representing admixture due to recent and historic migrations." Molecular characterisation and population genetics of the DYS458 .2 allelic variant G. Ferri, C. Robino, M. Alu, D. Luiselli , S. Tofanellid, L. Caciaglid, V. Onofri, S. Pelotti, C. Di Gaetano, F. Crobu, G. Beduschi, C. Capelli Abstract We recently found a number of intermediate DYS458 alleles, indicated as .2. This allelic variant is distributed in several populations, but currently no information is available regarding the molecular structure and the genealogical correlation of chromosomes with this variant. The molecular characterisation of such allele, its worldwide distribution and the correlated evolutionary history are the subject of the present paper. Molecular and genealogical data are suggestive of a single origin for the .2 variant. Phylogeographic analysis points to either a Middle East or East African origin, but additional data is necessary to clarify this point. Our results suggest that the .2 variants is a stable polymorphism and that it could be used for population studies. Copyright 2008 Elsevier Ireland Ltd. All rights reserved. "Haplogroup J* includes all of J except for J1 and J2. J* is rarely found outside of the island of Socotra, where it is quite frequent at 71.4%." Both J1 and J* are concentrated in the vicinity of East Africa/Socotra/Southern Yemen among populations who are biologically "Saharo-Tropical African variants". "While in this study, the paraphyetic family of DYS458 .2 chromosomes showed frequency peaks in North African, East African and the Caucasus samples, they differ in their within-paragroup phylogenetic arrangement. The East African pattern is likened to the latter pattern just mentioned, while North African and the Caucasus paraphyletic arrangements are just as mentioned above respectively, showing relatively more discernable within-paragroup [sub-clade] monophyletic relationships. The point of inquiry now, is to see if any potential "Middle Eastern" paraphyletic family of this haplogroup compares with that of the East African family both in terms of frequency peak and loose within-paragroup monophyletic relationships between the chromosomes." http://exploring-africa.blogspot.com/2009/03/working-hypothesis-around-haplogroups.html [/QB][/QUOTE]
