Koreans display high frequencies of the Y-DNA Haplogroup O-M176 . Genetic studies also found that, just like other East Asians, Koreans are almost very similar to their ancestors, the proto-koreans. Although few people claim that Koreans descended from several groups, a recent study show that Koreans possess a dual ancestry. The study says that Koreans have two genetic components; one from East Asia and one from East Asia or Northeast Asia. And Koreans weren't that homogenous at first, according to the study. They have had small amounts of admixture with ethnic groups like the Han Chinese, Yakuts, and Manchu.
Koreans display high frequencies of the Y-DNA haplogroups O2-M122 (approximately 40\% of all present-day Korean males), O1b2-M176 (approximately 30\%), and C2b1-F2613 (approximately 15\%) .
