Dr. Sykes in his recent book DNA USA, mentions this also that "this can be partly due to the Asia/Europe border artifacts of Siberian chromosomes rather than a genuinely recent European admixture." (p.315) He mentions a commercial lab that usually found around 25% European admixture in Native American samples. I think there is much more fine-tuning left to do and this article may contribute to solving the problem presented.Mark Dhttps://www.blogger.com/profile/03792117663748801194noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-19479946474108984362012-11-26T22:36:19.474+02:002012-11-26T22:36:19.474+02:00"...because we can be fairly sure that prior ..."...because we can be fairly sure that prior to 1492 there was no recent European ancestry in the Americas."<br /><br />According to Oxford professor of Human Genetics, Bryan Sykes, "European" genes have been present in North America for at least 10,000 yrs. He also quotes Mike MacPherson, statistician of 23andMe saying, that he calculates that pre-1492 Native American population in North America possessed anywhere from +/- 15-35% "European" genes.<br /><br />In practically all chromosome paintings of ~full-blooded North American Native Americans, some similar percentages of "European" 'admixture' is evident; also, in many Native Europeans whose families never resided in North America, a percentage of 'Amerindian' may be apparent.<br /><br />Does your analysis support their theories?shenandoahhttps://www.blogger.com/profile/09220865518565583662noreply@blogger.com
