Turkish Population Structure and Genetic Ancestry Reveal Relatedness among Eurasian Populations
Uğur Hodoğlugil1 and Robert W. Mahley1,2,*
“For example, supervised STRUCTURE (K = 3) illustrates a genetic ancestry for the Turks of 45% Middle Eastern (95% CI, 42–49), 40% European (95% CI, 36–44), and 15% Central Asian (95% CI, 13–16), whereas at K = 4 the genetic ancestry of the Turks was 38% European (95% CI, 35–42), 35% Middle Eastern (95% CI, 33–38), 18% South Asian (95% CI, 16–19), and 9% Central Asian (95% CI, 7–11). …. Thus, this study demonstrates admixture of Turkish people reflecting the population migration patterns.”
