Cinnioğlu et al. (2004) found many Y-DNA haplogroups in Turkey. Most haplogroups in Turkey are shared with its West Asian and Caucasian neighbors . The most common haplogroup in Turkey is J2 (24\%), which is widespread among Mediterranean, Caucasian, and West Asian populations  . Haplogroups that are common in Europe (R1b and I; 20\%), South Asia (L, R2, H; 5.7\%), and Africa (A, E3*, E3a; 1\%) are also present. By contrast, Central Asian haplogroups (C, Q, and O) are rarer. However, the figure may rise to 36\% if K, R1a, R1b, and L—which infrequently occur in Central Asia but are notable in many other Western Turkic groups—are included. J2 is also frequently found in Central Asia, a notably high frequency (30.4\%) being observed among Uzbeks.Y-chromosome distributions among populations in Northwest China identify significant contribution from Central Asian pastoralists and lesser influence of western Eurasians J2: 24\%. J2 (M172) may reflect the spread of Anatolian farmers  . J2-M172 is "mainly confined to the Mediterranean coastal areas, southeastern Europe and Anatolia", as well as West Asia and Central Asia. R1b: 15.9\%. R1b is found in Europe, West Asia, Central Asia, Southern Asia, some parts of the Sahel region of Africa.
