Facts

- The major components (haplogroups yE3b, yG, yJ, yI, yL, yN, yK2, and yR1; 94.1%) are shared with European and neighboring Near Eastern populations and contrast with only a minor share of haplogroups related to Central Asian (yC, yQ and yO; 3.4%), Indian (yH, yR2; 1.5%) and African (yA, yE3*, yE3a; 1%) affinity. (#14586639#)

- The most frequent haplogroup, yJ, splits into two sub-clades, one of which (yJ2) shows decreasing variances with increasing latitude, compatible with a northward expansion. (#14586639#)

- Haplogroups yG1 and yL show affinities with south Caucasus populations in their geographic distribution as well as STR motifs. (#14586639#)

- Frequency of haplogroup yI, which originated in Europe, declines with increasing longitude, indicating gene flow arriving from Europe. (#14586639#)

- Conversely, haplogroup yG2 radiates towards Europe. (#14586639#)

- Haplogroup yE3b3 displays a latitudinal correlation with decreasing frequency northward. (#14586639#)

- Haplogroup yR1b3 emanates from Turkey towards Southeast Europe and Caucasia.

- High resolution SNP analysis provides evidence of a detectable yet weak signal (<9%) of recent paternal gene flow from Central Asia. (#14586639#)

- The variety of Turkish haplotypes is witness to Turkey being both an important source and recipient of gene flow. (#14586639#)
