There is No Unique Turkish DNA

There has been an effort to convince American Indians and Mixed Blood groups such as Melungeons that they descend from Turkish sailors stranded on the Eastern Coast of America.

A convoluted explanation of how the Turks got here does not bear close scrutiny. It has been widely published that Sir Francis Drake dropped off a large group of Turks on his return from the sacking of Cartagena. There is not a shred of proof that this happened. And the much ballyhooed "DNA Evidence" does not bear out either.

It is now quoted widely on the Internet that certain groups in the USA have Turkish DNA. The article below from PubMed does not bear out that possibility. The suggestion is disingenuous at best.

The most important sentence in the article below is this:*The major components (haplogroups E3b, G, J, I, L, N, K2, and R1; 94.1%) are shared with European and neighboring Near Eastern populations* and contrast with only a minor share of haplogroups related to Central Asian (C, Q and O; 3.4%), Indian (H, R2; 1.5%) and African (A, E3*, E3a; 1%) affinity.

In other words, 94.1% of the DNA found in 523 Turkish Y chromosome samples is shared with European and neighboring Near Eastern populations. ***So there is no special motif orTurkish DNA.*** And this finding is explained by the closing sentence; "the variety of Turkish haplotypes is witness to Turkey being both an important source and recipient of gene flow".

Genes have flowed out and genes have flowed in for a very long time and cannot now be separated as belonging exclusively to one group or the other. So it is very deceptive to speak of "Turkish DNA" in the context of it being unique.

Analysis of 89 biallelic polymorphisms in 523 Turkish Y chromosomes revealed 52 distinct haplotypes with considerable haplogroup substructure, as exemplified by their respective levels of accumulated diversity at ten short tandem repeat (STR) loci. *The major components (haplogroups E3b, G, J, I, L, N, K2, and R1; 94.1%) are shared with European and neighboring Near Eastern populations* and contrast with only a minor share of haplogroups related to Central Asian (C, Q and O; 3.4%), Indian (H, R2; 1.5%) and African (A, E3*, E3a; 1%) affinity. The expansion times for 20 haplogroup assemblages was estimated from associated STR diversity. This comprehensive characterization of Y-chromosome heritage addresses many multifaceted aspects of Anatolian prehistory, including: (1) the most frequent haplogroup, J, splits into two sub-clades, one of which (J2) shows decreasing variances with increasing latitude, compatible with a northward expansion; (2) haplogroups G1 and L show affinitie s with south Caucasus populations in their geographic distribution as well as STR motifs; (3) frequency of haplogroup I, which originated in Europe, declines with increasing longitude, indicating gene flow arriving from Europe; (4) conversely, haplogroup G2 radiates towards Europe; (5) haplogroup E3b3 displays a latitudinal correlation with decreasing frequency northward; (6) haplogroup R1b3 emanates from Turkey towards Southeast Europe and Caucasia and; (7) high resolution SNP analysis provides evidence of a detectable yet weak signal (<9%) href="http://www.ncbi.nlm.nih.gov/pubmed/14586639">http://www.ncbi.nlm.nih.gov/pubmed/14586639">http://www.ncbi.nlm.nih.gov/pubmed/14586639
