A broad survey of Y-chromosome variation among populations of central Eurasia found haplogroup O-M175(xM119,M95,M122) in 31% (14/45) of a sample of Koreans and in smaller percentages of Crimean Tatars (1/22 = 4.5%), Tajiks (1/16 = 6.25% Dushanbe, 1/40 = 2.5% Samarkand), Uyghurs (2/41 = 4.9%), Uzbeks (1/68 = 1.5% Surkhandarya, 1/70 = 1.4% Khorezm), and Kazakhs (1/54 = 1.9%) . However, nearly all of the purported Korean O-M175(xM119,M95,M122) Y-chromosomes may belong to Haplogroup O-M176, and later studies do not support the finding of O-M175* among similar population samples (, ). The reported examples of O-M175(xM119,M95,M122) Y-chromosomes that have been found among these populations might therefore belong to Haplogroup O-M268*(xM95,M176) or Haplogroup O-M176.
