I have always liked the projection method (in which a DNA sample does not enter the PCA, instead is just projected onto that orthogonal space), but shouldn't it be possible to create this space with a large sequence, and then project the small a-DNA subset of that onto that space? (Here it seems that the space was created from both small a-DNA sequence subsets). The results then likely would be some probability distribution around a single point, but it seems to me that would be a fairer representation.eurologisthttps://www.blogger.com/profile/03440019181278830033noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-5261572090738188572013-10-27T16:02:13.628+02:002013-10-27T16:02:13.628+02:00They did not list the Danish sample's mtDNA ha...They did not list the Danish sample's mtDNA haplogroup, but when plotted over modern populations, the sample is closest to Finns and Northeast Euros.<br /><br />http://images.cell.com/images/EdImages/AJHG/ajhg1537.pdf <- See figure three for details.ZeGrammarNazihttps://www.blogger.com/profile/01668049133839073637noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-2088461041229728392013-10-27T15:17:51.841+02:002013-10-27T15:17:51.841+02:00So the ancient Bulagarian sits in the middle of th...So the ancient Bulagarian sits in the middle of the modern Germans.<br /><br />The ancient Dane sits in with the modern Finns (Hmmm).<br /><br />The ancient Incan? sits darned close to the modern Aymara.<br /><br />Pretty good continuity for a few thousand years.Anonymoushttps://www.blogger.com/profile/11000684388615334278noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-44833942899984165722013-10-27T08:25:21.648+02:002013-10-27T08:25:21.648+02:00So much the mtDNA U3b is a Gypsy haplogroup, it is...So much the mtDNA U3b is a Gypsy haplogroup, it is in fact old Thracian on the Balkans.

This person is from very early Germanic Nordic bronze age culture. Do they have any type of results in mtDNA and autosomal DNA.Krefterhttps://www.blogger.com/profile/01055804913528477710noreply@blogger.com
