DNA IN FORENSICS 2012: “EXPLORING THE PHYLOGENIES” 5th EMPOP Meeting 8th Y-Chromosomal User Workshop Innsbruck, Sep 06-08 2012 http://dna2012.gerichtsmedizin.at/files/DNA_in_Forensics_2012.pdf "Refined characterization of Portuguese mtDNA variability for forensic purposes" Rocha A1...

I think you misunderstood the post. What the study says is that 253,466 out of 805,958 (31,5%) newborns in France in 2010 have parents originated from a region defined at risk for SCD (mainly Africa, Maghreb, Antilles and MiddleEast) and therefore were screened (In Greater Paris this rate is 60%...

Since 2000, Neonatal screening for sickle cell disease (SCD) in France has been performed at national level for all newborns defined as being "at risk" for SCD based on ethnic origin. A new study posted in 2012 about "Neonatal screening for sickle cell disease (SCD) in France" shows that...

... and one more interesting detail that definitely proves that this "Mediterranean" is ... "Mediterranean" and not "European" at all. The highest percentage is DOD725 at 54.4%, from North Italy, right, but DOD168, a Tunisian, is... at 42.4%! so only 12% difference. This difference is too...

Very often in this forum and elsewhere, a few people try to demonstrate that there si no L mtDna haplogroups in Spain by quoting a study from Rhouda et al. 2006. "Human mitochondrial DNA as a molecular tool for population studies; the case of North Morocco", Rhouda et al. 2006. Indeed, it...

Dienekes is posting some of the more interesting abstracts from the upcoming ICHG 61st annual meeting in Montreal, in October. http://dienekes.blogspot.com/2011/08/ichg-2011-abstracts-are-onlineic.html Here is one we are definitely looking forward to: LD patterns in dense variation data...

In fact, here is a neighbour joining tree of the 12 components created by Dienekes to better illustrate this http://1.bp.blogspot.com/-llezDuKBAwM/TgDzprB0zuI/AAAAAAAAD2c/k89ILpspSac/s1600/nj.png As we see the Mediterranean clusters FIRST with SouthWest Asian ("Arab") and THEN with West and...

This Mediterranean component is obviously not "European" but just "Mediterranean" as its name implies. Indeed if we look athe Genetic distances Fst provided by Dienekes we can clearly see that "West_Asian" is closer to "West_European" (0.048) than "Mediterranean" is (0.058) is...

For many years people had wrong ideas about Moorish influence in Portugal. But recently, admixture and haplogroup analysis (Y-Dna and mtDna) on large samples both prove that Moorish admixture is real in some Iberian ethnic groups like Portuguese. "North African" admixture in Portuguese...

If the video shows the actual results of the Pharaohs and their haplogroup is R1b1b2, it is worth to mention that even if R1b1b2 is quite rare in modern Egypt (2% of the population), it is more frequent in NorthWest African where its frequencies are between 7-15% in some regions (Sfax, Tunis...

Autosomal african DNA in Spain (2009 study using 1.5 million SNPs) Autosomal DNA In a recent study in 2009, "Characterizing the history of sub-Saharan African gene flow into southern Europe", Moorjani et al. estimated the proportion of sub-Saharan African ancestry in southern Europe using...

New study about Zamora There is a very interesting new study by Luis Alvarez 2010 about "Mitochondrial DNA patterns in the Iberian Northern plateau: Population dynamics and substructure of the Zamora province". The authors found 10 L mtDna sub-saharan lineages out of 214 which gives 4.70% in...

Capelli et al 2005 "Population Structure in the Mediterranean Basin: A Y Chromosome Perspective" found the followoing frequencies (N=90) in Malta : R1b : 32.2% J2 : 21.1% I : 12.2% E1b1b : 8.9% J1 : 7.8% F : 6.7% K : 4.4% R1a : 3.3% E1b1a : 1.1% E* : 1.1% P : 1.1%

1) Casas found L3 sequences in Cordoba which are or course sub-saharan like all L sequences 2) Regarding Pereira et al. 2005, as specified, the 496 individuals from were not "left out" but were already included in other studies and in the data posted Quote from Peireira 2005 : "The Iberian...

To summarize, here are the sub-saharan African mtDNA L lineages frequencies found in Spain. This includes ALL the data ever published so far about Spain (1466 distinct individuals from continental Spain and 531 from Spanish Islands) 1) Continental Spain Spain, northwestern : 8/216 =3.70%...
